    I was researching off road shops for months before I even had any money. The time finally came where I was ready, so I started to reach out to a few local shops in the east bay to ask questions and get some information but many either didn't have the time or didn't want to help new customers. I then started looking outside of my local area and started sending out emails. Thomas was super helpful and recommended a few options within my budget. I finally pulled the trigger on his recommendations. I had originally installed the Bilstein 5100 all around on my 5th gen 4Runner but is was sagging due to added weight. So I went with Bilstein 6112 (heavy load) with SPC UCA's and 5100 in the rear with Dobinson's 325 coils. Effectively giving me a 2.5 front/2.0 rear and the truck came out EXACTLY how I wanted. The guys even went as far as to loan me a set of rear coils till my new coils came in and notched the aftermarket front skid plate because my KDSS was hitting it. I didn't even expect that level of customer service, it completely blew me away. Thank you guys for the awesome experience, You definitely will get my repeat business!

    There was no way I would pay the dealer's marked up price for an oil change and brake fluid flush. My warranty just expired for my BMW M4. Before this, I get my services done at Stevens Creek BMW. That is where I met Thomas. He worked on my car for the last 2 years and provided honest feedbacks and recommendations after every services. Last time I dropped off my car at Stevens Creek, he mentioned to me that he's opening his own shop and I couldn't be happier to know that there is an honest mechanic out there starting up his own business. I texted Thomas and he was able to squeezed me in with a short noticed. My first thought was the shop may not be busy since it is new. Well I was wrong. When pulled up to the shop, they had 5 cars ahead of me. I got to see many nice BMW and Porsches. While I sat in the nice AC waiting room while waiting for my car to be worked on, I can see through the glass door how Thomas meticulously service my car. Not only he worked on what I came for, he went through all of the inspections and also aired all the tires. I had a chance to meet his co-owner Jerry. It turns out he was a long time mechanic at Honda. Now I know where to bring my wife's accord to. I love supporting local businesses and I know they will do well. I didn't get to take picture of my car while it was on the lift but here's one of the customer's nice Porsche.

    Timing belt & water pump replacement completed
    Jerry H.

    Brought my car here for timing belt, water pump, valve cover gaskets, spark plugs replacement, and wheel alignment. Thomas went the extra mile and replaced some hoses and plug connectors that were damaged due to aging (car has 250k miles). Also fixed my leaking coolant issue. Competitive prices, honest work, super knowledgeable, clean shop, and friendly. What more can you ask for? Highly recommended.

    After lowering springs install
    Kelvin T.

    Was a little skeptical about coming to an off road spot for my ev. But they work on everything! Was looking for a spot to do an alignment since I had all 4 tires replaced. Flex function was extremely responsive and quick to do the job. No questions about who I wanted yo install my lowering springs and do another alignment. Great work!

    New Method 314 with Falken RT. Plenty of trimming to fit 37s!!!!
    Ian G.

    By far and wide the best body shop I've ever dealt with. The communication and attention to detail is unmatched. I've gone to plenty of other shops and Thomas and Jerry are the best period! I'm actually pressing them to do other jobs on my truck that are probably outside of what they normally do because I'm tired of dealing with shoddy work. Thanks a million guys

We were referred to Campbell Motor Center, and the experience exceeded expectations from start to finish. On a Thursday evening, we spoke with Anthony, who went out of his way to get us scheduled for the very next morning. That alone was impressive, considering the dealership couldn't get us in anytime soon. By Friday, the car was in, serviced, and completely finished within about four hours. The pricing was about one-third of what Mercedes-Benz of Stevens Creek quoted us, without sacrificing quality or professionalism. What really stood out was the level of service. Anthony handled everything personally, from communication to updates. Every question we had was answered clearly, and we always knew what was going on with the car. No pressure, no upselling, just honest and efficient service. With over 30 years of experience in customer service and running a business myself, I don't give this kind of feedback lightly. This is an A++ operation. Going forward, every vehicle we own outside of dealership warranty will be serviced here. Highly recommend. Frank Saunders

I bring all my cars here for regular maintenance like oil changes, brake fluids, differential fluid and coolant fluids maintenance, brake pad and rotor replacements. They've also handled bigger repairs such as an axle seal leak, valve cover gasket leak, and fixing warped rotors. Everything has always been done right the first time. What really sets this place apart is that Anthony does most of the work himself, and after the job is done, you hear directly from him about what was done and why. He's very polite and easy to talk to, and you never feel like you're being ripped off. The quality is as good as--or better than--the dealership, using original Toyota parts, but without dealership prices. No middleman, no customer service rep--just straight answers from the person actually working on your car. He also documents major repairs with before-and-after photos and will even check in a day or two later to make sure everything's driving well. Most importantly, they're honest, reliable, and trustworthy. I've never had an issue in the 10+ years I've been coming here. If you're looking for a shop you can actually trust, I highly recommend TLS Auto Service.

I'd been to 2 other shops with my 94 Camry trying to get the problem resolved. Both of those shops got my car in an accident while test driving it. I ended up losing out at both places, besides neither one could fix the computer problem and kept getting computers from junk yards. Finally after the long diagnosis, over 2 hours at Rensons, they figured what it needed. A NEW computer, which worked fine, and if I'd only known that's what it needed, I would never have gone to the awful places I chose before Rensons. They charged more than I expected to diagnose the problem, it was in the hundreds, and then the computer out the door price was close to 2k. But it came with a guarantee, and a smile and honesty. I would choose Rensons if you want knowledge and can afford to go there? Not cheap, not even really reasonable, but they fixed my car, so got to give credit where it's due. Giving 4 star because it cost more to diagnose than 1 hour, which shouldn't have happened. Over $300 just for a diagnosis. The place is clean and they have a decent waiting room area. I might go back there, but it would depend on price. They do good work, and they tried to fix the door which had been dented and stuck closed, besides the other 2nd place also messed up the glove box, so they realigned it and it looks perfect. They really did a good job on what was handed to them.
