Steve and Allen know what they are doing! I've had puzzling issues with my '66 Mustang (after market A/C quagmire)and my '55 T-Bird (speedometer and hard cold start ). Things I just couldn't figure out as a seasoned amateur. I bow down to these guys. They are gurus. They are not cheap but they will certainly get the job done. Ronald Wacek read more

The guys picked up my 70 El Camino for new suspension, motor, exhaust and AC. Steve, Alan and Cris are extremely knowledgeable, take pride in their craft and on top of that they are great guys. Their prices are a little on the high side but trust me it is well worth it. They far exceeded my expectations. My car is now an awesome show worthy beast! Like they say you get what you pay for! read more

American Performance - 1970 Chevy El Camino 396 SB Stroker - Auto Repair Near Me - Pleasanton, California

I have now taken my 72 Nova in to Steve and Allen twice for a dyno tune on my new Holley Super Sniper EFI system with Procharger. They found some fuel delivery issues that Holley tech support could not identify, let alone offer a solution for. Allen quickly solved the issue and ended up getting a very dynamic tune for me that increased my power significantly. I drove a 3 1/2 hour round trip both times and would not take my car anywhere else to be worked on. Great guys to work with and very fair when it came to billing. They are the Real Deal!!

My Cobra replica was running just ok. I took it to Alan and Steve. They found 40 HP and fixed a couple oil leaks. Highly recommended.

I brought my 1956 Bel Air to American Performance for many different upgrades. Thank you Steve and Alan for all the service and hard work job. I highly recommend American Performance if you want the job done right. read more

American Performance - 1956 Bel Air - Auto Repair Near Me - Pleasanton, California

Brought my second vehicle to Steve and his crew and he knocked it outta the park again on my 70 chevelle. He upgraded everything from new 383 stroker, fuel injection, suspension, transmission, and everything in between. He now has a dyno onsite which dials in maximum HP. I am very happy with his work which he stands behind and would highly recommend this shop to anyone looking to get their car done right the first time. read more

First let me say I found American Performance by way of a prior customer and he raved about this place. Not long after I ended up purchasing an old school and the seller took me, selling me a lemon with an engine that failed 50 miles later! [That's another review that will be coming soon ;)] Bottom line is I found myself in uncharted water and needed an honest and reliable mechanic to help me out. I remembered American Performance and gave them a call. Steve was over the top knowledgeable and took the time to help me understand my options rebuild-vs-crate. It made sense for me to purchase the crate engine and he ended up installing a ZZ502 for me. It's been nothing short of magic since with Zero problems. A few important points of note- * Steve went far beyond what good customer service is. Providing outstanding and frankly refreshing customer service. * I needed help getting my car to his shop and he picked it up and loaded it on his trailer without any hesitation {Same Day!!!}. I mentioned I did not want to leave my car at the shop [I wanted to work on it while the engine was out] and he was glad to return my car to my house while waiting for the engine to be delivered and picked it up again to install the engine once it arrived at his shop. Free of charge! * From the time the engine was received at the shop to the time he installed and gave the BEAST back to me was only 2 days! * Steve is by far the most knowledgeable mechanic I have ever met and is willing to take the time to * After the engine was installed he called me a week later just to check on me and make sure the car was still running and there were no issues. [Very much UNLIKE the car dealer mention before was all too willing to wash his hands of me] * Lastly I ended up having a trany leak that Steve took care of me for dirt cheap and had me in an out within a couple hours. The bottom line is this place is legit and although prices may be slightly higher than your run of the mill shop the work that is performed is guaranteed and will be DONE RIGHT. Steve has created an honest shop that does great work. All of my cars will be taken here as long as this shop stays open. Give it a shot. The worst that could happen is you find a trusted mechanic that does a great work. read more

I can't give enough positive feedback for America Performance. Steve and Allen are true professionals. I took my hotrod to several shops prior to A.P. but I got nothing but problems and wasted money elsewhere. Steve fixed all of the problems that I had and got me running right! And talk about working quickly. Seriously, they are very knowledgeable about everything that I could throw at them. Make your appointment now because they book up quickly. read more

I've been having trouble with my transmission even though the place doesn't work on my type of car STeve was kind to refer me to another spot. He went out his way to check on the situation and give me some great feedback! Thank you Steve! read more

Steve and Alan and the rest of the crew are the real deal when it comes to maintenance or high performance tuning of your classic muscle car. Pretend that you are walking into a mad scientist lab with all the cool shit and your vehicle will come out meaner and faster than ever. Make sure to pay attention to the details of all the work they perform it's out of this world. These guys are not cheap so be prepared, but there is saying you pay for what you get!!! If you want Quality take your car to American Performance. You want cheap and economical take your car to Amco read more

To many issues to list ! Really don't like writing reviews so I will cut this short and not go into details. The guys are basically nice guys , but always in a hurry, charge way to much and seam to be learning on customers cars how to install what they sell. So many issues, I have had to remove my new 25K engine three times to fix what they did. Save yourself a lot of grief and don't go there. read more

I was getting my 1979 Jeep CJ5 I just bought smogged at the shop right next to Steve's place. During the inspection, the engine just crapped out and refused to start again, leaving me stranded. I popped into Steve's shop and asked if they could take a quick look and let me know if it was a dead battery or something else. Turns out it was "something else". 30 years worth of tinkering with vacuum hoses connected improperly, two fuel pumps trying to push fuel through a clogged fuel filter, two batteries connected to each other in series draining each other and making the alternator work over time, etc. Steve and his guys got to work in the parking lot right then and there and less than 24 hours later I had a new alternator and belt, a properly connected (and largely new) vacuum hose system, batteries that were actually rigged up properly, and overall a car that could start without brake fluid being added to the carburetor. Everyone at the shop was extremely knowledgeable, friendly, honest, straightforward (Steve flat out told me he wanted nothing to do with working on that Jeep - but he couldn't leave me stranded). I would use these guys as my go-to mechanic in a heart beat, but he specializes in muscle cars and that's what he wants to do. If you have one, absolutely trust your car to these guys. You won't be disappointed. read more

I have taken my 66 Mustang GT to American Performance for several years now. Steve is clear about what the problems are and does even extra things that make improvements as part of what he does. He loves cars and knows his stuff. I have referred several friends to him. Steve McKinley read more

This is the place to go. Steve is very knowledgeable. He always takes very good care of us and takes pride in his work.

Was very pleased with the work done on my car I brought my son's car in too. He fixed a problem with my son's Cadillac that many other shops were unable to fix. Steve is an excellent mechanic and I will be bringing all my cars in and recommend him to my friends and family. read more

For Steve and Allan at American Performance... Brought my 1981 Chevy show truck in for Carburation issues after upgraded engine replacement, they were able to identify several vacuum leaks that only appeared under technician procedure testing as well as a worn Carb . The problems were taken care of. Truck runs GREAT ! , got my moneys worth . read more

Shout out to Steve and Allen for tuning my 97 Ford Mustang Cobra. I found that finding a shop to tune my car was more difficult than I anticipated--especially a reliable and honest one--until I found American Performance right down the street from my house! They inspected the car, buttoned it up and put a nice and manageable street tune to go along with the blower set up it has. I definitely will be taking my car there in the future. Thank you guys! read more

I was sent to him with my MG when I first moved to the area. I say "him" because this is a true owner op shop. Steve will take care of any car you bring to him and even come get it is you can't get it to him (for a small charge). The name of the place is American, but he works on everything. read more

From an italian friend of mine who was living here for 6 months: I'm an italian guy and I was in the USA for two months. I had a problem with the Mass Air Flow (MAF) sensor of my 1998 Hyundai Tiburon. All the mechanics told me it would be at least $150 only to read the code of my car: eventually I arrived to Steve's garage. He was so nice and fair. He read for free the code and said me he would help me when I had to fix it. Finally I fix by myself (very easy), but I came back and give a bottle of wine to Steve. A great American person who helped an Italian poor boy... read more

Man I accidentally came across this guy let me tell u this guy is full of knowledge. If he can't find a part he will build it.the item will be original and look sick as heck. He also works on anything and everything. You wont leave with a hole in ur wallet read more

American muscle cars are Steve's passion, but his knowledge extends to almost every make and model known to mankind. Most importantly, he will fix your car with quality parts at a fair price. In addition, Steve is willing to take on the challenge of fixing your car when the first two mechancis you took it to wouldn't touch the job. He also has the ability to custom-make a part if need be. I take all of my cars to Steve. read more

I first met Steve in 2002 when he restored my dad's 1970 El Camino SS. Steve is professional, honest and very straight with you, which is hard to find in this industry. He has done an amazing job on all of my cars without breaking my bank. Thanks Steve !!! read more

I was new to the area and my car stop on freeway so I found them on google as near place to fix the car and Steve look at my car and told me don't worry it's will be ok and he fix my car so fast . He is best !!! read more

What can I say, other than Steve and his Team as a rare breed. I was stranded in Pleasanton with a clogged Cat. Even though the shop was officially closed, Steve went out of his way to get my car back on the road and over the hill into San Jose. At first he didn't want to be paid, but I insisted. I highly recommend Steve and his team, they treat you like family!!!!! read more

Steve and Allen have worked on my muscle cars for several years now. They go above and beyond to help the customer out. For example, yesterday I had an appointment to have my 70 GTX looked at because it was making a racket in the transmission. I get in the car to start it and nothing. I know the battery had a good charge because the lights were working. I called Steve to let him know and he offered to drive over and take a look. Who does that? A mechanic making a house call? Fortunately I'm close by and they showed up 15 minutes later and helped me chase down a broken ignition wire and get it started. They called me a couple hours later and said the problem was the flex plate and it was fixed. They have also sorted out fuel issues on my resto-modded 63 Vette, rebuilt my 6 pack carbs, etc. They even rebuilt the top end on my Challenger T/A after a different shop screwed up the rebuild. They are busy but they do quality work. read more

I took my 1970 Camaro to Steve @ American Performance after I read the positive comments in Yelp. Steve speaks the language of cars and is truly passionate about what he does. He is very knowledgeable when it comes to cars and knows exactly what it needs and how to remedy the problem. I look forward in bringing my car back to Steve and continuing the car relationship we started!! read more

Steve is great! I only had him change the fuel filter but a lot cheaper than going to the dealer (duh). When I arrived he didn't have the filter in yet so he drove me to work and then called me when he was ready -- just a few hours later. It felt like the "old" days ... he didn't mess with paperwork but dealt with me as a valued customer. He will be servicing my truck moving forward! read more

Steve was great! I went in to get some recommendations and thoughts on some noises I was hearing. He got me squared away in no time! The guy loves cars and it really shows. Thanks Steve! read more

American Performance....doing it right. I bring all my vehicles to this place. Be it an oil change or high performance custom work. Steve and his crew can do it all. American, exotic, foreign, and domestic. Give him a call and check it out for yourself! Honest people, honest prices. read more

10-16-13 American Performance, wow what a job they did. I have a 1966 Chevelle Super Sport 396 big block that run rough as hell, road like hell and didn't stop very good. Steve diagnosed the trouble for the motor running bad, as the cam was too big for a stock 396 motor. He recommended that we replace with a cam that was closer to a stock cam which would let the motor idle at less RPM. He also said that by changing the cam it would increase vacuum which would activate the power assisted brake unit which wasn't functioning due (o vacuum) to the larger cam. As far as the rough ride the original builder raised the car by putting over size coil spring in which made it ride like a chopped Harley with a ridged frame. Steve suggested replacing all the coils spring, shocks and front lower and upper control arms with Detroit speed equipment. Everything he suggested we did and it runs, handle and stops like a new car. GREAT JOB!!!!!!!!!!!!!!!!!!!!!!!!!!! read more

American Performance is the place to bring your classic car - Fair prices and quality work! Steve is the most passionate mechanic I've ever met - his passion is getting the job done to the highest quality possible. Pete is a great mechanic who did unbelievable detailed work making the car purr and look fantastic! Pete and Steve did great work on a challenging job - Fuel Tank and Radiator on a 67 GS400. Finding the right fuel tank and manufacturing the filler neck was difficult to say the least and it looks beautiful. Then, getting the right radiator to keep the car running cool even in the heat of the Diablo Valley - and it looks cool as hell, too! And because the radiator needed a big new generator to power the new electric fans, they rewired the car - so now not only does the radiator look shiny and new, but the entire engine bay looks awesome! Fantastic work, good & fair prices and they worked extra hard to get my car back to me in time for the long weekend! Steve has a customer for life in me for maintenance and restoration/upgrades! read more

I have a really nice Bronco - but definitely no thanks to this guy. He took the job (putting a new engine in) and re-doing the electrical. He kept it for over 2 years, constantly putting me off. Giving me every excuse in the world. Mind you, I got all the parts, including the engine delivered and FULLY built. All he had to do was put it in and get the thing running. Something he claimed he was the best at. He sold my old engine out from under me, he lost a ton of my old parts - which as you vintage car guys know, I could have sold. He made a ton of excuses and even cried. Basically, I ended up having the police come by so I could get my Bronco back. I had another shop put it together and get it running. I'm guessing he used to be really good, but something went wrong and now that shop is just a wreck. It took me a year to write this because I wanted to write something useful to the next person instead of just venting my anger. Be very careful. read more

Steve and his team are simply the best at what they do. They know cars, the engineering and technology of modern and classic vehicles inside and out. I own 6 classic stock and resto-mod muscle cars and have worked with several other shops in the area, which are good at what they do, but if you want to have someone work on your car that understands how things work systemically to optimize performance in the right way, bring your car here. Steve continues to amaze me with his knowledge and ability to proactively fix issues that you would have never known about. Highly recommended! read more

Best place to bring your car if you want it to run better, HANDS DOWN. I needed to get my Camaro smogged in 2 days to get it sold. American Performance got the job done and I was able to get my car smogged and sold when he was finished. These guys can do anything at a quality level. Recommend to all! read more

I had recently purchased a '67 Chevelle from a local shop and ran into problems the day I was supposed to drive it back to San Diego after picking it up. I talked to Steve and on short notice and on a Saturday, he picked up the vehicle and went out of his way to make sure everything was good to go in only a couple hours for me and my family to drive it back. OUTSTANDING SERVICE. WOULD RECOMMEND TO ANYONE!!! Big thanks to American Performance for their help. read more

I had an incredibly awful experience with Steve. I went their because my car broke down and someone suggested their and I went to get my car fixed. Steve ended charging someone else's tab, and did not make a report for my car. The employees were not respectful nor professional by any means. Steve offered sexual favors for "help" and was very demeaning towards me. His colleagues weren't much better. I was very offended and extremely upset by this. My boyfriend called their number to talk to Steve and he was not at all respectful, kind, and offered no help. We later found out that another colleague had been reading private messages between Steve and I from his so called "business phone". This company has clearly violated many laws and my privacy to say the least. Who knows how many other guys were reading private messages through Steve's "work phone." If I had the chance I would definitely sue him and their company for fraud, and several other things. I've never been so astonished by incredibly rude and unprofessional people in my life. He continues to try and talk to me, claiming he cares and I had no choice but to block him. He uses people, money, and belittles women. Why stoop to that level? I am extremely disappointed in their services and want to warn others of this terrible matter. If you would like to discuss this with me you can email me at lovesdaisymae3@gmail.com. People in cali really are stuck up assholes who only care about money. read more

I just got my car back from the car whisperer Mr Steve La Fountaine from American Performance and I could not be more pleased with the work and attention to detail that he showed my car. I had so many issues with the chevelle to the point where selling it was looking pretty good, but when I drove the car from his shop I quickly changed my mind. I have worked with a LOT of mechanics that do just enough to get the car back on the road for a short while, but not Steve. He gave my car greater longevity, performance, and also gave great recommendations on future projects. He got the car running better than it ever has before. After my visit with American Performance, no one else will be looking under the hood of my car in the future except for Steve! read more

Steve was aggressive about what needed to get done. Final product was more than I had imagined my car could obtain in terms of power....engine totally woken up.

Kicks ass from go now....revived my 1967Pontiac GTO muscle car to the bully she is on the road. Good job! read more
