Hidden fees, they use aftermarket parts and they have illegals, working for them.And you take advantage of Women, customers!

Dan, the owner, runs a great business. I have been going to Zimmerman Auto for more than 20 years and I have never had a problem. The service is outstanding, the prices are extremely competitive, and Dan is one of the most honest individuals I know. read more

definitely not a happy with the service brought the car in I bought my own BMW parts so I would not get over charged so I bought the water pump thermostat coolant later it went out. I know it was something that they did, all they said was you need to get a engine so i check around for engine labor payed installments when came to pick car up lights dash window battery frm module damage two weeks later car broke down luckily bmw of catonsvile fixed it later I found out Zimmerman shop never put back the bosh spark plug and coil they put some bull shit denso read more

They don't fix their mistakes. They left air in my coolant system that led to a blown head gasket and a seized engine, then refused to accept responsibility. We were customers for over 10 years. read more

WOW!! RUDE 0 Stars minus 100 stars if had an option! how are you in business!!!!! Please save your money and never use them!!!! they mess with the wrong person!!! I had to call the cops today on them. The guy behind the counter told me to shut up and get out the shop. I didn't say anything disrespectfully to him. All i ask was why are you typing so much for an invoice that should been ready 2 weeks ago. ALSO he tried to charge us an extra $500 that i never agreed on. If you take the car to a dealer for a second opinion, it's on YOU. The agreement is between you and the dealer it's not the customer responsibility if you can't fix the car. They are thieves. Cops came for me to have something in writing to take them to court!!! read more

I was very frustrated with my BMW garage and decided to look for another garage. A friend of mine recommended Zimmerman so I decided to give it a try. Dan, the owner, is nice, courteous, responsive (he communicated well via text messages which is a big plus for me!) and serviced my car this morning. All went well, I plan to continue to use his services in the future! read more

***BE AWARE - DISHONEST MECHANIC **** At Zimmerman (7638 Airpark Rd) they LIE to your face about cost of repair and apply charges without informing you!!! They performed unauthorized diagnostics on my BMW that did not even fix the problem and charged me for something that they did not even fix. They said they had to tow my car for a 2nd opinion (again with out my knowledge and approval) and that I was now responsible for the cost of the $350.00 tow. DONT TAKE YOUR CAR here...there are other mechanic shops in the area that will get the job done in a professional and honest manner. read more

Honest mechanics who have never tried to screw me over (irrespective of my gender), like other shops/dealerships.

I didn't even have to buy anything to know the owner and operator was a man of upstanding character. I was in the market for servicing the 722.9GTRONIC transmission in my 2013 Mercedes W212 E350. Previously I had gone to euro motor cars in Germantown to buy the parts, the price I got from Zimmerman automotive, including parts and labor, was less than what the dealership wanted for just parts! read more

I've been going to Zimmerman for 12 years and they've never let me down. The prices are reasonable and they do good quality work. I never feel like they do more than I need. Dan's an honest guy and I appreciate what he's done for me over the years. read more

I have had work done here in the past when I lived in the area. When my father asked if I knew anyone who could look at truck & do good with fair pricing I instantly thought of Zimmerman! My father is a difficult person to please yet when the work was done (same day) he was in a good mood & thanked me for the recommendation. I figured I'd share our experience for anyone looking for a reliable shop to work with! read more

Service is unmatched. I came during peak hours and was serviced before I could even sit down. Everything from customer service to the work done on my vehicle was top tier. Any question I had was quickly answered. The only downside is just finding out about this place. Thankful that I did! read more

Took my car for an oil change and experienced a good experience! Enough parking, clean waiting area, seats to wait outside.. The guy was honest about what my car needs not like dealerships! I waited like 30-35 minutes. I will def return back. read more

Mechanic left his dirty gym equipment all over my car - gloves, jump rope, and sweaty towel. Owner is totally unaccountable. Avoid this place!!!! read more

Took my BMW car to Zimmerman and should have a 1 year warranty, he won't honor it, he said he changed the head gasket and found out by BMW ROCKVILLE was never changed. It still has the leak And won't fix it, I spent over 4K fixing my car by this company, and now he wont fix it. Be careful he will take advantage of people and women who don't know much about cars. Ended up Had to pay for the same service because it wasn't done right and he won't honor his warranty. This was the worst experience I have ever had. There was a couple arguing with him in the lobby about the same thing, this should of been a red flag, I'm sorry I ever took my car to this shop. read more

My family and I have been coming to Zimmerman Automotive for years. They provide excellent service every time.

Brought my car here for service as it was recommended to me by the previous owner of the car. I left my car with the understanding of a 2 hours service and 5 hours later they never called me to let me know it was ready. When I showed up the guy was not courteous. read more

I do my regular car maintanace here, the service is professional and the customer service is friendly. Very good experience.! read more

This is my third visit to Zimmerman Automotive and every visit since the first has been so great that I have found my new home for my BMW service needs. They are professional, courteous, responsive, timely, and have the utmost integrity. A bonus is that the very inviting waiting area is state of the art with comfortable chairs and a cell phone charging station with cables. read more

Fast and efficient service at a good price. Would recommend to anyone driving a Toyota.

My go to car service place. They always have everything I need to service my car and I never had to wait, if I go early enough I get the car back on same day. The best ! read more

I've been coming here for a few years and Zimmerman has provided consistently good service. I have Toyota Camry and its still in great condition thanks to great regular maintenance by Zimmerman. Only downside is that wait times can be lengthy and there's really not much to do around the shop. They do offer complimentary coffee and tea and free wifi while you wait. Overall, i'd definitely recommend. read more

I have been coming to Dan's shop for years. He has always taken care of me, from the time a deer tried jumping my car to the most recent visit today when I managed to lock my keys in my car as I was getting out after getting there much later than planned. No matter how hard I've pushed my luck, Zimmerman Automotive is always able to fix it up like new. They truly are miracle workers! read more

I suppose I should be grateful that car-abuse isn't a crime, because I abuse my car. A lot. Oil changes? Only once a year. Tune-ups? Unless that has something to do with getting an iPod dock installed in my car, I'm not interested. Topping off fluids? Uhh, gas is a fluid and that's as close as I'm going to get. As for the body of my car...well, I'm not an Asian female driver for nothing (yes, my driving is what started that stereotype)... Needless to say, my husband has bravely undertaken the Herculean task of maintaining my car which has been made a little easier with Zimmerman Automotive. Prior to bringing my car to Zimmerman, my husband got a quote from another garage. To change my timing belt, water pump and a couple other things (not including checking out my AC - which has been dead for 2 years, but I can't be bothered to get it fixed), it would cost around $900. Yeah, I won't get into the huge lecture I got about how if I just maintained the car, it wouldn't have cost so much...but honestly, if you rack up the cost of the maintenance, plus how much time out of my day it would take to deal with this, and the annoyance of it all - I think $900 is super cheap. But I digress. After getting the quote, my dad recommends Zimmerman's because the wife of the owner is a customer of my dad's. So our relationship is nil, however, as it's only a block or so away from our house, my husband decided to give them a shot. To do the EXACT same work as detailed on the quote by the other garage - Zimmerman charged us $475! Yes, $475, not $900!!! THEN he also took a look at my AC and filled it up with some magical AC coolant thingie for $60. He also says that my AC compressor thingie is shot - but that it'll probably last for another year or so, so if we wanted to, we could wait (which was magical music to my ears while my husband got a migraine from trying to convince me to fix it now...yeah he lost)...so we got the car all fixed up for around $550! My husband also brought his car in to get his tires changed, which ended up costing about the same as other garages, but the huge savings that we got on fixing up my car has definitely made us a fan! read more

Quality, Wait Time, Customer Service "Great, honest service" Dan is the consummate professional, his estimates are succinct and fair. His team of hard workers and totally efficient and produce excellent service. I would not take my baby ( BMW Z4 3.0 sport edition) to any other place. I hope he never retires!!!!!! You purchased 1 item on July 5 for $#%^ read more

I will be very honest. I started to take my car here because I was tired of being charged more at the dealership. You get what you pay for. I never got much done here. Oil changes mostly. I've been getting oil changes done here for about 6 months. Last week my Check Engine light came on so I took it over. Zimmerman's couldn't read the code from my engine and recommended I take it to the dealership. Okay. I get that. What the dealership found was horrifying. There was oil EVERYWHERE. The cause? Botched oil changes. Old, recycled oil. My oil supply seal worn away. Oil all over the Camshaft sensors. Hoses ruined from burning oil. The oil filter was COVERED in oil. That sort of thing doesn't happen overnight. But wait, there's more. Zimmermans had also done a 'tune up'. Change of spark plugs, the works. What did the dealership find? Factory issued spark plugs. THEY DIDN'T CHANGE JACK SHIT. I ended up spending over $1,500 on repairs that resulted on botched jobs from Zimmerman's. $1,500 because Zimmermans didn't take the time to do it right. Simple things that if they had done a proper oil change and proper tune-up, I wouldn't be paying for. Repairs to the Camshaft sensors, hoses, gaskets (which were MISSING...uh, HELLO?), oil plug seal, and top engine cleaning. Because there was sludge everywhere. If you want cheap maintenance and repairs, by all means go here. But you will get what you pay for and it'll cost you more down the road. Zimmermans will be lucky if I don't walk into their shop demanding every penny I spent on them back and show them the "new spark plugs" they put in my car. read more

Received top notch customer service from making an appointment on the phone to the day I got my car repaired. I'm a loyal BMW owner, and I used to go to the dealership up until now. BMW dealership had one of the best customer service and products. But on my last visit to the dealership, I was disappointed with the repair cost. I went to Zimmerman after reviewing on Yelp, and they gave me a list of things to fix in order of priority. So far so good and thanks for the refreshments and comfortable couches!!! Keep up the great work. read more

Saw the check-in deal for $5 off an oil change and the 5-star reviews so decided to check em out. Went in for an oil change at 11:30am on a Friday, which was later than I had wanted to get there and fully expected to have to wait. I was pleasantly surprised when they said they could take care of me right away, especially after seeing the garage looked pretty full. The deal saved me $5 off of $25 I guess to make the oil change $20. It's not THE best deal around, but it's still hard to beat and a great value IMO if you don't have to wait that long. Afterwards the guy didn't try to sell me on the other work that needed to be done on my car and simply pointed out the information on my invoice, which I appreciate. Overall great and fast oil change experience. read more

This place is a gem. I was in a pinch to get a battery replacement for my Bimmer (battery lasted me over 6 years so this was a first time replacement). My experience all started when Dan (the owner) answered the phone. He was very pleasant and I did not feel rushed, like I did with previous calls. I even called him right back with another question and he was extremely helpful and patient. I asked if I could come in and have the battery replaced same day he advised that I could without hesitation- even though it was close to their closing time. Once there I continued to bug him about things I needed for my truck and I even asked if they could perform an oil change really fast- Dan's response- yes. I was pressed for time and they had several customers ahead of me and they still got me out of there in about an hour. Although great service is extremely important to me I have yet to get to the most important part...they are REASONABLY priced. I don't think I've ever said that when talking about my truck. This is surely my new service center. This place is worth your time. Take your car here. They will take care of both of you. read more

These guys are nice, no-nonsense mechanics. When they gave me an estimate they were thorough with what they thought was wrong, and why. I felt like I was getting an honest answer, not some fluff-piece upsell. For $767 I got the water pump and brake booster fixed, plus another $100 to get the spark plugs 'n cables replaced (a possible reason for why the car would lug when accelerating from a stop). The car runs fine now and is very responsive. Despite the distance I will gladly go back to Zimmerman Auto for future car issues. the only drawback is that it can be easy to miss where the business entrance is. perhaps a flashier sign would help? Eh, no big deal. read more

I came about a half dozen times between 2016-2018 because I wanted to try a new place for oil changes. The first thing I noticed was that they take a LONG time. I think my average oil change time was around 2 hours. Their labor prices are pretty reasonable. I had them replace my engine accessory belt on my civic for $90. However, now it squeaks pretty regularly. They always had a "recommendation" about a problem my car needed fixed. First they told me my front axle seals were leaking and could take care of it next time for $387. After getting that taken care of they told me my valve cover gasket was leaking ... $200. I got fed up with the long service times so took it to my old mechanic. First thing he told me was that the oil pan drain plug had been glued in place with some kind of sealant, and when he took the sealant off, the plug almost fell out. Apparently Zimmerman stripped the drain plug threads and rather than telling me, just decided to cover the problem with sealant. Obviously this wasn't a pre-existing condition because if it were, you can bet Zimmerman would have told me immediately so they could charge me for it. And I asked my new mechanic if there was any oil leaking around the valve gasket. Would you be shocked to hear that they detected no oil leaking from the gasket? The car got healed! It's a miracle! Before I started coming here I saw a few negative reviews, but figured the people must have been picky or done something wrong. Now I guess I'm one of them. Based on how the owner likes to discredit negative reviews, I can't wait to see his response. read more

I was in today to get my oil changed, tires rotated and air conditioning fixed. Dan saw that my windshield wipers were pretty shot, so he replaced those too. It looks like my air conditioning is an electrical problem, so instead of having me sit there all day, I'm dropping it off later in the week, so they can spend more time on it. I just love that there's never any pressure to have work done. Dan does what has to be done at a very reasonable price and let's me know what to expect next. Tip: If you need to get your MD inspection, this is where I got mine when we first moved to the area. read more

Honest and flexible. Is that possible? Yes. I had to get my car MD inspected and I called Zimmerman based on the Yelp reviews here. Not only did he honor the time that I could bring the car, but he also honored the time limit he said it would take (30 mins). That means a lot to me because I've been to mechanics who say bring your car in now and you race over to find 10 people ahead of you. Or been told that it'll take an hour and you're frustrated that 3 hours of waiting has gone by. And the waiting room? I felt spoiled a bit. It was a nice waiting room, with coffee, but the best part? It was clean! I've done my car waiting purgatory in the dingiest of places and I felt like I accumulated more germs and dirt than service. As for the owner? Friendly and competent. This is my new automotive place. read more

When I moved back to Maryland, I was looking for an independent workshop for my Audi A6. My car pushed me further to look for a shop, when I was informed by other mechanic that the twin turbos have seen the end of their life. I found Zimmerman through Yelp, and Dan checked my car and informed me of the same, but the response and quote I got from him sounded more honest than the other guy. I took a chance and got both my turbos,water pump, and timing belt replaced. This work is more complicated than it sounds, as for this particular model of A6, you have to pull out the engine to reach the turbos. I got the car in 3-4 days, as promised by Dan. He got me the original Borg Warner turbos with warranty and even showed me the boxes of it and my old turbos, without even asking. Of course, as honest as he is, he reduced the price of turbo cores from the final bill, again without asking. I have taken my car for regular maintenance to him since then, and even though it is 42 miles away from my house, the peace of mind in knowing that an honest guy will be supervising the work done in my car, is well worth the drive. So, if you have an import that is eying your wallet, give a try to Dan and save some money and hassle of dealing with dishonest shops. read more

100% satisfaction guaranteed is a gimmick on their card. They misdiagnosed my car, saying I need a intake manifold (which I did not), and charged me a lot of money. The same malfunction code stayed on. Owner did not care. When I brought it to another mechanic, it was something minor, which had nothing to do with manifold. read more

This is my fourth time here. Everytime I come, Dan is accommodating and courteous. Reasonable prices for my bmw oil change. When I came for my brake pads change, he showed me the price. I shopped around and it was cheaper by almost 25%! I've encountered no problems and great prices so far. Now that my bmw is out of warranty, I'll probably just keep coming here. read more

I have been a customer for about 10 years, Dan always provides an excellent and reliable service. Highly recommended.

Stop searching for your next mechanic! This is where you need to go. I was introduced to Mr. Zimmerman by a business partner of mine. What started as a simple inspection for one car-has turned into an everlasting relationship built of trust, respect, and loyalty. I WILL NOT TAKE MY CARS ANYWHERE ELSE!!! I have had all 5 of my cars and cars of my family and friends taken care of at Zimmerman Automotive. Dan Zimmerman is the most honest, trustworthy, stand-up individual. He will make sure you are updated and clear as to what is going on with your car, what it will need to get fixed, and will go about fixing it in a VERY QUICK turnaround time. The waiting area is clean, quiet, and temperature controlled with fresh coffee. I couldn't ask for more and will continue doing business with Zimmerman Automotive. Simply, THE BEST! read more

Well this will be my second and final review of Dan Zimmerman. He is a complete idiot. Where to begin, well I'm sure as soon as this is posted, if he sees it, he'll surely want to give his 2 cents as he does when anyone writes a negative review but here we go. I own an 07 Audi A4 which began having problems one morning on my way to work. The car stalled and didn't want to turn on. Assuming that I had somehow damaged my own car, I had it towed to Zimmerman instead of the Audi dealership......WORST MISTAKE OF MY LIFE! First off, for anyone who has brought their vehicle to Dan, knows he's cold and unwelcoming so if you're concern is customer service, DO NOT COME HERE. Anyways, they initially told me the issue was minor and could order the part and have the car repaired in a couple of days. Then I received another call from Dan and oops, they actually found sugar in my gas tank. So that was actually the issue. He was informative, I'll give him that, so he told me to contact my insurance company to see if the repairs would be covered. Thankfully they were willing to cover the repairs and everything seemed like it was going to be ok...... I picked up the car and immediately smelled gasoline. Since I picked up the car after they had already closed to the public, Dan handed me my keys and I paid him, so I went around back and drove home. I thought the smell of gas would be temporary but it still bothered me so I called him the very next day. He told me it may have been one of his mechanics that spilled "something" and to "just roll the windows down"....The smell continued each day until one morning while filling my car with gas, I saw a huge spill underneath my vehicle. Now this was just about a week later that the spill occurred or at least the first that I had noticed it. At that point I called Dan immediately to let him know, but of course he wanted to take another look at it. I'm not too sure if anyone else would be interested in taking their vehicle BACK to the shop where it was supposedly repaired for them to attempt a second repair. Fool me once.....right? So naturally I took my vehicle to the Audi dealership. We all know dealers just want your money and try to rip you off. Well in this case I had no worries because I had assumed my insurance company would take care of the issue. I would later find out that would not happen. Well the dealer informed me that there was still sugar in the gas tank and Zimmerman DID NOT repair my vehicle correctly or even followed common procedures for this type of issue. I can go more in detail but there's way too much information. The dealer broke down specifically what had happened and what Zimmerman did not do correctly. Now keep in mind, me and the dealer both assumed my insurance company was still going to cover the repairs, so I never felt they were leading me on or attempting to rack up repair costs. They simply told me Zimmerman didn't do the job properly. Later on I contacted Zimmerman and Dan accused someone else of tampering with my vehicle. Of course a shop owner who repairs a vehicle incorrectly is going to make any excuse why after only a week, the car is still having issues. I moved forward with the repairs at the dealer and because my insurance company said I was the one who chose zimmerman auto for the initial repair, they wouldn't be able to cover a second repair. I tried fighting with my insurance company, which by the way is GEICO, but a second adjustor who actually works on cars told me that Zimmerman didn't repair the car properly and I could either take it back to them or pay out of pocket. I care way too much about my safety and my passenger's safety to have taken it BACK to zimmerman after they had supposedly fixed the issue. All I need is to be driving down the highway and have someone throw out their lit cigarette onto a trail of gas leaking from my car. The dealer even presented pictures of the sugar still in my vehicle, showing they didn't complete the repair. On top of all that, the Audi representative offered to contact Dan to see what he had to say. Of course Dan excused himself and said that his mechanics ran the car for days and no sugar was left in the car. The repairs cost me about $4000. I'm sure Dan thinks he's heard the last of me, but to me, that's a lot of money. I later filed a grievance with the Better Business Bureau but of course, Dan excused himself once again. Dan needs to learn to treat everyone with respect and maybe smile, it's not that difficult, you own your own business and I'm sure you make a lot of money. Don't claim the repairs were completed until in fact they actually are. Be honest and trustworthy, that's all. These are people in your community who you're taking for granted. We live here and we bring you our business, treat everyone right. I'll never recommend Dan to anyone and in fact, I tell everyone I know NOT to go there. read more

I called last week to schedule an appointment to have my front bumper repainted. I was advised I can drop of the car Monday, 4/27/15 at 8:30am. I arrived at 8:30am and there was no one there. I see the sign says they open at 9:00am. I decide to wait and by 9:15am the office still isn't open. I wait a little longer and a young guy comes by and says no one is coming till 3pm. This company has no respect for their customers. Don't schedule people and decide not to come to work. Now I have to fight with the rental company about my rental car and find another shop to fix my car. Thanks for leaving me high and dry and costing me time and money. read more
