I was so pleased that David was willing and able to get my car diagnosed and repaired... and super fast! When my check engine light came on, I initially took it to the dealer for a diagnostic (nearly $300). They told me it was my head gasket and it would cost $6700 and take 2 weeks to repair my car. Thankfully, I said no and took my car to Car Science for a second opinion. David found that it was not the head gasket, but in need of spark plugs and a new ignition coil. The dealership tried to take me for $6k. I am so grateful to David at Car Science for his expertise and honesty. I'm back on the road, the car is running great, and I will happily return for all of my vehicle's needs. read more

In today's world with car dealership service departments, you are made to feel like just another person in line to have their car fixed. This is why you appreciate places like Car Science because the person behind the counter, writing up the repair form is the same person that will be working on your vehicle. I have been dealing with David all these years and he provides direct assessment on what needs to be performed on all my vehicles. This is what I appreciate most as I've been burned before by dealerships having parts replaced and service done where it was not needed. If you live in East Bay, this neighborhood shop is worth checking out. They don't just repair cars but execute regular service maintenance too, so whatever car brand you drive come see David and crew. read more

I took my Land Rover Discovery there for inspection and I was very happy with the work that they did, Mar who was the tech, was very helpful and educated me on what I needed to have done for my vehicle. The customer service was great and I will definitely use this company again. read more

Great place, David will take care of you and offer you a honest competitive quote for whatever service you need on your vehicle. I have a European car which some mechanics don't have the expertise or knowledge to deal with. They garentee their work and will also give you an honest assessment. I have repaired my car there and they have switched my oil housing gaskets and CTS. Great work read more

Integrity, honesty, thorough explanations, and quality are the words I would use to describe this place under David's ownership and supervision. It is how it used to be when you could rely on a repair shop to help alleviate car stress for the average hard working individual! I have been taking my car in for several issues now that are occurring probably due to the ever growing, poor quality and craftsmanship of car making happening since the pandemic! He is responsive and explains things thoroughly which I appreciate. Their prices are reasonable. read more

Car Science is an incredible auto establishment that really cater to customer satisfaction, fair pricing and work being completely in a timely manner with high quality standards. David was super knowledgeable in the car problems that I was experiencing. Really appreciative of all the hard work being done in my car! read more

David and the whole staff at Car Science are awesome. I've taken my vehicles there at least a half-dozen times, and I've been happy every time. They are honest and take pride in their work. When David has found an issue that he knows I can fix myself, he asks me if I would rather do it myself to save some money, and even walks me though the process. I've been looking for a long time for a good mechanic that I trust, and I found just that at Car Science. read more

Years ago, I took my daughter's 2005 Nissan Sentra for an engine oil changed, after it was done, I drove it home while on the freeway the car started smoking and when I got home, I pulled out the dip stick and found out was dry no oil in the engine. I drove it back to the shop and told the people there what had happened and one of the guys there started blaming me that I drain the oil myself, isn't this a stupid accusation? why would I put my own daughter in a harm's way. Figure it out! I don't think I can rate this shop for an oil changed. read more

5 stars!! I recommend Carscience to all my family and close friends. This family owned repair shop is honest and a must try if you live in the local Bay Area. I have taken everything from off road trucks, modified sports cars, and all of our daily driven vehicles (domestic and import) to David for over a decade. David is highly experienced and excellent at diagnosis. Doesn't hurt that he has a solid team of techs to support him. I've blown up my track car and was able to drop the car off on a Sunday and leave the keys in the drop box so they can check it out when they open on Monday. They takes care of customer cars and I always feel safe leaving vehicles in his care. Their waiting area offers comfortable seating and free WiFi while you wait for your car to be ready. I do recommend giving them a call or email to schedule your service. Honest shops tends to be quiet busy so you can assume they have multiple large projects currently being worked on. read more

I was referred to David by a friend. I have a 2001 GMC Denali and had David work on my drivers window that would not open. I also had his repair my exterior door lock that somebody broke during an attempted break in. This was the tricky one. Since my truck is so old, he had a hard time finding some of the clips that hold the lock together. David had to fabricate a few pieces. When he finished everything worked as promised. Great Work. I'm going back real soon for items on the list he recommended we complete before winter. Thank You David..... read more

David and his crew really did a good job on my car maintenance. The whole family go there for our car maintenance.

David was great. He took care of my smog problem. My check engine light came on, so knew that there was a problem. After researching several service repair companies, I decided to go with Car Science. Tina was very helpful with explaining to me what was causing the issue ( catalytic converter ). David verified the problem, ordered the parts and completed the repair in a timely manner. His shop will be my go-to shop for all of my vehicles. read more

I've taken my vehicles to David and his crew at Car Science for years and will continue to do so. They are honest and upfront with the quotes, and they get it done when they say it will be done.

They offer timely recommendations and what to plan for in the future as far as maintenance and repairs go. I highly recommend Car Science. read more

Car Science was recommended to me for car repairs. I was thinking of trading in my BMW X5 for a newer car but they fixed her issues and now she runs great. They addressed the issues I had and then recommended a few reasonable things that my car needed and I felt a major difference when I drove my cars after repairs. I highly recommend Car Science, they are friendly, accommodating, and honest. They are my go to repair shop now! Thank you Car Science! read more

Great customer service!!!!! Sending all my cars here. Appreciate all the help and honesty. Great people here.

Finally found the best mechanic! David found a transmission for my Mitsubishi Lancer for half the price three other mechanics were quoting me. I couldn't believe how badly the other guys were trying to rip me off. After a year of driving my car I have no issues. Thank you David for all your hard work. I will be back for all my car maintenance and issues. You guys are the best! read more

My boyfriend was a regular at Car Science for the maintenance of his Tacoma truck for the past year. He really respected the business and felt 100% comfortable taking my Mercedes there for a major repair job. After spending $1500 the car drove like new. the next day upon leaving the shop the check engine light came back on during our morning carpool to work. My boyfriend took it back in and found out it was an emission part that was not working properly. He received a quote on paper to have it repaired for $524. The next week I took the car back to have it repaired. I personally called and informed David who I was and that I would be there Saturday morning. I had never gone into the shop and my boyfriend had taken care of all details the first time. When I arrived my car was fixed within an hour. However the issue occurred when it was time to pay for services. David provided me with a bill for $790 even though he had quoted on paper to my boyfriend that it was $524. I was shocked! I provided the paper quote that my boyfriend had received a week ago for $524. David quickly changed the price from $790 to $555. In the end I was disgusted that women are still being taken advantage of for auto repairs. My boyfriend trusted this business and trusted that while he was out of town on military business that I would be treated the same way as if he brought the car in. That did not happen and Car Science lost 2 loyal customers and their friends. read more

I've been going to this shop for about 3 years now. I've brought them 4 different cars to be worked on and the outcome everytime has been phenomenal. The first time I ever stopped by I brought a 2012 Silverado in to have the brakes checked since I was told they needed changing. I was assured and shown that the brakes had a good amount of life left. I now bring my mustang in to get serviced and always leave with a great feeling. I recently had all my lines flushed and refilled, brakes changed, and rear diff fluid changed. The difference when I got in the car was immediate. These guys know what they're doing. Very humble and honest. read more

A Mechanic you can truly trust! There are several local auto mechanic businesses out there, but it is so hard to find a mechanic you can really entrust with your car. David and the guys that work at Car Science are awesome! They do a good job because they really know what they are doing. I take my Honda to David all the time for repairs, tire changes, and tune ups. He always advises me on what I need to do to keep my car safe and running properly so it will last me for a long time. He also saved me from spending money I didn't need to spend couple months back when another mechanic scared me and told me I shouldn't be driving and I needed to change my breaks. I brought it to David for a second opinion, and he told me truthfully that I was still able to drive without replacing the brakes for another 2-3 months!. I Just recently brought my car in to get my brakes fixed, tires rotated, and transmission fluid changed and I feel much more confident now taking my car out for longer drives. My safety comes first and David always insures that. Plus the setting in their shop is nice and clean, well kept up that I don't mind waiting in there to get work on my laptop done. Tina that helps out inside the reception desk is also very nice and very pleasant with all the customers and the rest of the local community. He also will be helping me replace my visors that broke off in my car, and wont be charging me crazy labor prices vs what the dealer would charge me. Thanks David and to your team of trusted mechanics!!! read more

So I am a 22 yr old woman that was taken advantage of (financially) elsewhere, and that place still didn't fix my problem. So I show up here at Car Science and meet David, and right away I am given straight talk. David basically figures out how to trouble shoot my problem (O2 sensor), cause I needed to pass my smog test. The previous location simply replaced my part for a RIDICULOUS fee, and basically said ok good luck. After David worked his magic for less an hour I was left both happy and pissed. First, I was happy that he fixed my problem, but secondly I was pissed that the first place charged $600 when I should have paid around $100. Lesson learned and now I know who to trust, and that seems to be rare in automotive repair. So if you want a straight shooter at affordable pricing then PLEASE go see David at Car Science. I am now a customer for life...thanks David! read more

I've been bringing my cars to David for service since 2013. All my experiences with him and his shop have been great. He's helped me with a number of things - from selling a car and towing it at no cost to the most recent service on my son's G35. He always goes above and beyond which is why I continue to return to his shop. Thanks David and staff for the awesome service and all of the assistance! It's hard to find mechanics you can trust and those that provide great service. read more

I have been having my vehicles serviced here for a couple of years. They do good work at a fair price and I feel they are honest with their recommendations on services/ repairs needed. read more

Amongst the entire mess of getting proof that my car won't pass smog at the DMV, these guys made it a bit easier for me. Originally I was going to go to another place right across the DMV but the guy working it was a complete disgrace, disrespectful and very rude to me. I've taken my other car here a year ago to have it smogged and they did a pretty good job. David helped me out and was pretty straightforward with me. My check engine light has been on for over a year and I don't wanna spend $1000 on a new catalytic converter. I just need proof that it won't pass so it gives me an extension period so I can get a new car. I told him this exact story and he didn't try to up sell me on anything or try to see if he could fix anything. Smog and out, that's all I needed and these guys provided it. When I came in it didn't seem too busy. These guys are underrated if you want honest service come here, you won't be disappointed. read more

This is in response to the comment posted by the business owner. I have not returned nor have I tried to contact the business again. I'd like to clarify a couple more details, especially fact versus opinion, and close the matter. First, the facts: - None of the vehicles that were listed in his comment was the vehicle that my original review was based off of. My review was based off of the service on my boyfriend's car. I recommended this business to my boyfriend because I was satisfied with the service before the business change. - I posted about the wrong oil being used because according to the car's manual 5W-20 is the suggested oil. According to the receipt that was not the oil used. - The owner did privately message me wanting to respond to my concerns and was very transparent about how he takes my review seriously. He also was upfront about contacting him to address the issue and also provided the contact information to report fraudulent service. Fact&Opinion: With regard to the brake pads, it was claimed that they need to be replaced for my boyfriend's car. When brought to another auto repair shop, that mechanic said that they didn't- so it comes down to the opinion of the mechanic. Fact: my boyfriend has had no brake problems since the oil change service without any replacement of the brake pads. My opinions: - I realize in the owner's comment that there are alternate oils that they may use depending on the environmental conditions, without necessarily being "wrong." My suggestion is moving forward to confirm what oil, if different from what is suggested in the car's manual, will be used before the service is performed. - I do feel that this business wants to make right and I appreciate the follow up and diligence to respond to my original review. Thus, I increased the rating two stars because of the intent to improve; they welcome and want to resolve customer concerns. read more
