Go meet Billy for a great quote and Anthony, Raymond, Richard and Robert will have your vehicle on the road quickly at a reasonable rate. And best of all they won't steer you wrong read more

I wish I could give them 0 stars I brought my car here to get a starter replaced and wouldn't do it because the intake was off the car.

Brought my 2005 Silverado in because my A/C was dead and blowing HOT. I felt confident that Anthony could work on A/C and he found another issue during my initial visit the day before. He found it was something simple with the A/C and made the other repair. I drove home chillin with it being 98° outside. Great guy great staff! read more

I have a 2007 Infiniti M45. I used to go to Niello's Infiniti in Concord for repairs and oil changes. About 3 years ago, I was told I had a gasket leak towards the rear of my car that would cost over $3000 to repair. I asked if it was an emergency and I was told by their mechanic that I did not need to do it for about a year. Well, turned out the leak was the radiator and hoses! Went to MTZ Auto Repair and they quoted me a very reasonable rate. Got my car fixed and I l will be back because I need struts and shocks now. This isn't a fancy place where they offer you water and snacks and that's fine by me because I'm there business done and that's what they do! read more

I brought my car in for a minor cosmetic repair and they noticed I needed new breaks and rotors. Not only did they go above and beyond to get me in that morning but they were helpful, knowledgeable and professional. On top of that the pricing is super reasonable. I highly recommend this place to anyone in the area. read more

I really can't say enough good things about this place. I've had 3 major things replaced on my car in the last few months. Every time I've dropped if off I've gotten a call back within an hour with a quote on what the repair was going to cost. They also have been able to fix my car that day which was awesome. I highly recommend them for anything you need done to your car. read more

I trust these guys so much. They saved the day for me today after my dear husband installed my battery incorrectly and two AAA guys from two separate calls couldn't figure it out. Anthony took one look at the battery and then the owner said "okay you can drive home now". I was floored. The car was not starting, every error message it can send, it was sending, lights were flashing. It was awful! I spent all afternoon freaking out, even one of the AAA guys told me he thought I was "in trouble" because he's never seen an Explorer wig out the way it did. I was already canceling my commitments tmrw because I thought it was going to be really bad. They didn't charge me anything and I am so relieved! I've been using this shop for 6, maybe 7 years now and I refer everyone to them. They are all so kind and they do honest work! I love MTZ!!! Cookies coming soon, guys! read more

Great service and highly recommend! Stumbled upon this place by random, and since ive been a returning customer!

Clutch job done on 2001 Subaru Outback at a better price than elsewhere and more importantly, with no issues since over 2 years ago.

My go to shop to work on my vehicles. I take them here for service, repairs, and oil changes. Some real good folks here.

My old vehicle was having some issues. I could just tell something was off. I brought it in the MTZ and had them take a look. Unfortunately they couldn't find anything. The put some time into trying to see what the problem might be but couldn't find anything. The second time my check engine light finally came on. I immediately brought it down for them to take a look. Fortunately, it wasn't too bad and the prices they charge for repairs are incredibly reasonable. My truck ran great after they made the repair. Then sadly months later I had a catastrophic valve cover issue. I called them to see if they could repair it but I realized that the issue was not worth the money to put into my older vehicle. So now I have a new vehicle and I wouldn't hesitate to bring it in to MTZ for future repairs. They treat you and your vehicle great. read more

Again.... So impressed.. Actually a shop ran by honest, helpful, awesome people. Thank you!!!! Had truck fixed there almost a year ago and began seeing same problem, it happens. Dropped in to discuss and was treated so well. They fixed it right up without cost same day.. We have 5 cars in our family. All of them will be brought here. read more

I took my car there for the first time two weeks ago for an oil change and a fuel filter change. Great service and pricing. Other quotes were twice as much as I paid. This is a small low key place with great customer service!!! read more

I'm not typically a yelp review type person. But felt the need to do a big shout out to Robert and the crew at MTZ Auto Repair. They are always accomodating and very knowledgeable with whatever goes on with my little ole 2005 Infiniti. Most importantly, I trust them. I will never take my car to anyone else. read more

I had another issue with my car and I always take it to Anthony because he is really good and I trust his judgment. Anthony and Billy was able to get it fixed and didn't cost me an arm and a leg. Thank you both for an awesome job. read more

Fixed my car for 1/3 the price of other repair shops. Good service and done faster than any other repair shops I have gone too!!! GOOD JOB MTZ read more

I have had mainly AC services done on multiple cars here. The prices are great and the work is done so fast. It's fantastic, every time I have had something done they finish it same day. read more

This repair shop has nothing but excellent service. My family has been using mtz auto repair since 2010. Everytime weve took our vehicle for repair theyve done an outstanding job and was never any problems. A big shout out to mtz auto repair, robert the owner an honest stand up guy! We'll be lifetime customers definitely!! read more

Always a good experience! Four stars because they don't have weekend hours and couldn't fix my husband's car's A/C. Maybe the car was just a lemon and it wasn't them? Everything else has been fantastic. read more

Buyer beware, especially if you are on a budget. We normally go to the dealership to get services done but I received a coupon in a mailer for MTZ Auto Repair, for a 29.99 oil change and tire rotation so decided to try them out. My husband took the car in, dropped it off and presented the coupon. When we picked up the car later he was given a 99 dollar bill! They chose on their own, without calling us, to change from regular oil to synthetic oil, a 37 dollar up-charge, changing out both the cabin air filter and regular air filter for an additional 36 dollars. They did rotate the tires per the coupon. To top everything off we now have a loud vibration sound coming from the cabin air filter area whenever we run the fan and cannot figure out what it is. Maybe they dropped something into the fan motor when they were changing out the filter? Going in thinking they will honor their coupon and then being surprised at pick up by more than a 300 percent increase without being called and given a choice to have the work done is scary and unprofessional. We will not be returning. Buyer beware. read more

If your car breaks down in front of their shop tow it somewhere else! They ARE NOT honest!!! I paid for an A/C hose that they never replaced. When they finally replace it after all our van shut down on the freeway. $1200 later it has left me stranded two more times not being able to pick up my kids. It still is not running right. It ran fine prior to taking it back for the A/C......They are incompetent and SHADY! I'm sure this review will not be here for long as they chose which stay on Yelp read more

I've been taking my vehicles to MTZ Auto for a number of years now! They are super helpful and always take the time and care necessary to make me a happy customer! I recommend them highly!! read more

Very disappointed. I called around for estimates for a major repair and MTZ offered the best price I could find. When I showed up for the actual repair, the guy at the desk quoted me over $1000 higher than the phone quote before even looking at the car and with no new information since the phone call, so I left. Would they have done good work? I'll never know. read more

Did my homework on yelp and found favorable reviews for MTZ auto, and It is right next to my house. I originally called back in September to price out a timing belt and water pump replacement for my 05 Toyota Sienna. He was WAY under other quotes I had received. I called back 2 weeks ago to see if the price quote was still good and took my baby in. Not only did he stick to the wonderful price, they gave me a complementary oil change and had it done 1 day earlier than they initially stated. My husband was floored- he went out and checked the work (making sure belts were new) and said it looked great. He had just had a coworker tell him he paid 4times as much for the same thing on his Ford Explorer. We will now be loyal customers! read more

This place totally saved me! I drive daily on Hwy 4 between Martinez and Hercules. I live in Sacramento though, so I don't know any of the local Martinez service providers or anything. So, my 2003 Saturn L300 suddenly dies at 9 am on a Monday morning. I'm stuck on HWY 4, and I don't know to whom to have it towed. YELP to the rescue! I called one highly reccommended mechanic shop in Martinez, but he was too busy to even be able to look at my car and referred me to MTZ. I called MTZ and they were so nice! Very professional, and genuinely concerned about me and my time. By 1030 the tow truck had me in the shop and by 1045 I was out with a very reasonable fix-it estimate and a commitment to have my car ready by 330 THE SAME DAY! By 3pm I received a call saying my car was ready. MTZ delivered EARLY! Nice! Turns out my serpentine belt shredded and that's why I overheated and couldn't steer (the belt drives all the pumps for the various car functions like cooling and power steering). MTZ replaced it, was clear and fair about the costs, and most importantly, did it in less than one day without hesitation or premium. FYI--I googled typical replacement costs and MTZ was right in there with what was to be expected to replace a serpentine belt on my make and model car. And they didn't try to add "rush" charges or make any attempt to get more out of the situation. I highly recommend MTZ. read more

I have put off writing this review for too long! Anyhow, I was first referred to MTZ Auto by my aunt about a year ago. After years of taking our vehicles to big chain repair shops I decided I would give them a shot. My first experience was with a Check Engine Light--I was taking a trip to Tahoe and wanted to make sure my suburban wasn't going to leave us stranded on the mountain, so I asked Robert to diagnose the issue and make sure the truck was in good shape for a strenuous trip. Maybe about an hour (if that) later, I get a call from Robert telling me everything is done and I could come pick up my vehicle. I walked out of there feeling great about my truck and spending about a quarter of what that big chain shop would have charged me. I've since taken it back several times for oil changes and brake jobs and have always received nothing but 5-star service. I love everything about this place--I've since referred everyone I know here...and I know at least four of them have since gotten work done. Every one of them has said what a great experience they've had--great work, great customer service, and great rates! You really can't go wrong :) read more

I gave this company at a five stars. I had an emergency with one of my vehicles they took care of it, got us back on the road in a timely manner. With in 3 hours. Great job MTZ we'll be back. read more

Update. MTZ Auto gave me a refund for the work they could not complete. Thank you Billy for doing what was. right.

Robert saved me! It was Saturday afternoon and I was on a trip when my transmission started doing bad things. I found MTZ on Yelp. Despite the fact he was supposed to be closing soon Robert had me bring him my car. (There were very few other options for me on a Sat. In this part on Martinez - everything was closed.). It turned out I was Very lucky! He took my car and pointed me in the direction of good food. After just a couple of hours he had diagnosed and fixed the problem - which was relatively minor (and fixed my hood latch for me!) and did not try to make up some more complicated problem! It was clear I knew little about cars, was stranded and was at his mercy- and he did not take advantage. He was extremely friendly, professional, and his work was fairly priced. I don't think I will ever be in that area again to use MTZ again - but if I lived nearby that is where I would take my car. read more

Been our mechanic for over ten years! Have referred friends and in laws! Wouldn't go anywhere else!

Service.. Service.. Service. I've been going to TMZ for a couple years now and no matter the cost of the repair Rob has you leaving happy you came to him. A Professional threw and threw. He isn't always the cheapest but they make sure you get ever pennies worth in service for your money. And not only that he goes above and beyond. Checking fluids checks other things as he works on your car. And Speed of service. Yes, all the other reviews about how quick he gets your repairs done are true. If it's not a huge issue (like a cracked head gasket) he will squeeze you in as best as he can to get you on your way. If you want it done right With A+ Service this is the place to go! **********5 Starts doesn't do MTZ Justice********** read more

I've brought my Lexus in because my check engine light was on, and requesting an oil change using Mobil 1 and tire rotation. Robert never called to tell me what was wrong, or for me to ok him to work on it.. I called 3 hours later wondering what was up and he said it was done and had no oil.. weird how my low oil light never came on and my car was still drivable..he changed with some bullshit oil when I specifically said Mobil 1.. and charged me to the tune of 153.83... No tire roation, bullshit oil, and 100$ for checking my engine light... when I told him their website and picture right here on yelp said 20$ for check engine light, he started arguing and telling me bullshit and showing how dishonest he and his shop are.. Thanks for waisting my time you shady piece of shit. I'll let everyone know not to come here starting with this review.. read more

I Just looked at my car license plate holder and they took my holder off of my car then put theirs advertising mtz auto with there phone number on it. I looked at my husbands car because we have had both our cars there and they did it to his car too. This is unacceptable. I called and asked them did they do this. When clearly they did. They said oh yea only with permission after asking, and I tell them you did not ask me and I don't like that. I called my husband and they never asked him either. Sucks cause I was happy with them but to me this is shady low bs. Im not paying you to force me to be your advertising wtf! Your loosing business with this b.s. read more

Thank you to MTZ Auto Repair. My carpet cleaning van had a leak in the radiator. They were fast, affordable and reliable. I strongly recommend MTZ Auto Repair. read more

You know what my favorite thing about MTZ auto repair is ... EVERYTHING!!!! They are a bunch of bad ass mechanics that do a great job in a timely manner for a fair price. They never bullshit me , I love them !!!! They had me up and Running with a new heater in 1 day no more cold babies on the way to school in the am !! read more

Today was the day I had my car serviced at MTZ and was I impressed, first I called and made an appt. but incorrectly wrote my date wrong but got a call from Will and he reminded me it was for today. I got a very reasonable quote for a new timing belt, water pump and basic tune up. While being serviced they found a few issues that needed to be fixed and called to inform me first. I have to say I thought they would hold my car hostage for several days but no it was ready in about 3 hours. They provided me a lift home and when I picked up my car I met the owner Robert, very nice and was not afraid to introduce himself as the owner. The service level was top notch for such a small shop and the quality of work was excellent. I don't think you will find a fairer price around town and I will be doing all my vehicle service there from now on. Thanks to all the folks at MTZ! read more

Well I lost the review I was typing for MTZ. It was long and I was almost finished. I hit the wrong button on my computerr. I won't go into details again, but needless to say they are very great and wonderful and HONEST. Instead of installing an expensive part to get my car ready for smogging, instead all the mechanic did was reset my 02 sensor, test drove it and sent the paperwork to DMV! And charged me a nominal fee. After I left I went and bought a 2 lb box of Sees candy for them! Trust this is the greatest auto repair around!!! read more

I was referred to MTZ for our car repairs and we live down in Dublin. Robert, the owner, is fantastic. He is a tell it like it is, don't screw you over kind of mechanic. He is honest and true to his word. We have been there twice now and will continue to drive 20 miles to get our cars serviced here. Our check engine light was on and he diagnosed it for free and reset it for free. They did a follow call, asking how our car was after it had been serviced, which you rarely get anywhere else. I highly recommend MTZ for all your car services. read more

BEST DEAL IN TOWN ON OIL CHANGE!! I got my oil changed for only $33. This is their regular rate. Very friendly, great reviews and a small business that I feel good about supporting. They use a nice blend of synthetic and natural oils. They got me right in and were done in 30 minutes. So happy I found them!! read more

Took my truck to MTZ after another shop told me they couldn't find the problem. MTZ took the truck without an appointment and had it fixed within 4 hours, fair price. 5 stars from me, they are great, read more
