If youre looking for honest, trustworthy and friendly service then Jose Martinez and his staff at MTZ Performance Auto Repair are the folks youre looking for. We drive 35 miles from the East San Gabriel Valley to Gardena, passing countless auto repair shops because we know our vehicles will be well taken care of. We trust them with everything from tune-ups to major engine repairs; they maintain our Hummer H3, GMC Yukon Denali XL and our restored 1977 Chevy Crew Cab Dually. We have recommended them to everyone we know who needs excellent service with very reasonable prices! Jose saves all of the old/repaired parts and shows you exactly what was repaired. Highly, highly, highly recommend!

Very honest mechanic. Have sent several people to him and they are always pleased.

Very good service and trust, thanks!!! For your service

Jose Martinez delivers excellent work. He is taking perfect care of my cars. Great service, affordable prices, friendly, honest and knowledgeable.Highly recommended!

Super..dedicated crew.

Busy shop but very attentive and helpful. Told me the possible issue, and steps to troubleshoot and turned out to be the first thing they said. Highly recommend.

Every mechanic in their garage was very polite and very professional. Every staff member gave me a polite greeting and wanted to help as soon as I walked into the well equipped and modern garage. Everyone on the team were knowledgeable beyond expectations. After they reviewed what needed to be fixed, I instantly saved over $600 from the estimate I got from a recomended shop called A&J auto shop on Crenshaw that tried to rip me off until I drove over to MTZ performance auto and got an honest estimate.. I recommend that everyone take your vehicles to this Garage because they are all straight from the hip and want to help. The owner(jose martinez) is somebody that you including my self will keep as their mechanic for Life..Joshua Olson

DO NOT GET YOUR CAR FIXED HERE!!!!!!!! They replaced my coolant tank but DID NOT PUT THE CLAMPS ON?!?! How ?!?! The tank exploded & ended up breaking more things within the car car because of the pressure. When I called & let them know he said ITS NOT HIS PROBLEM. How is the job your paid for not your problem??? DONT GET YOUR CAR FIXED HERE!!!

I paid them for a replacement part on my car. They did not properly install causing a domino affect of other problems with my car. This happened not even a few weeks after I paid them to replace. When I called back for a refund (because I would NEVER allow them under the hood of my car again) he got loud & started yelling it’s not his problem. HOW IS IT NOT?? Don’t waste your time, there are plenty of shops that will treat you right!

WOW TERRIBLE SERVICE! & I don’t mean customer service only, they did NOT fix my car properly. I would not recommend

I dont know where these other people went, but my experience here was the worst service Ive gotten from a mechanic ever. The first thing they did was lie to me. I asked if they did transmissions, they said yes. Turns out that means they hand it over to another shop nearby to do the work. They said itd take 4 or 5 days. Then it was next Saturday. Then Monday. Then Tuesday. Then in two hours. Then tomorrow at noon. And when I finally showed up they lied and said it was in the car wash when it was clearly visible in the other mechanics garage, being worked on still.And I had to initiate contact every time. At no point did they call me for anything other then to demand a deposit. I showed up then got told to wait more. And more. And more. Lie after lie.Oh and I can tell just from the sound of my motor they didnt do the tune up right. But Ill take that to a different mechanic because I want nothing to do with these people ever again.

I dont go anywhere but MTZ because they have the friendliest staff, best prices and know what theyre doing! They will even give you the best advice to make sure you get the most out of your car and avoid the same mistake. This place been taking care of my baby for almost 3 years now and they will do everything they can to fix your car before recommending you to the dealership. I even brought my sister here to get new brakes and oil change and she was happy with the results and the prices! Even after moving an hour away I still come here. Jose and Miguel you guys rock!

Very good customer service and excellent service to my 06 Tahoe.

My experience here at Mtz Performance Auto is a great one . I came about 2 months ago for an engine swap on my 05 acura rsx and the job was done quick and very good i took a while to write the review because I wanted to see how good the work was and the work is greatcustomer service is the best Ive ever got and the great part was during the swap the owner would call me to tell me what was going on he also called me in to see how the work was going the crew and the owner are very professional and helpful . greatest experience Ive ever had I highly recommend them .

This place is awesome they can fix any car and wonderful costumer service and the most important they are honest * * * * *
