 Trustindex verifies that the original source of the review is Google. Wonderful experience all the way around. Did a diagnostic on my older Lexus and provided a detailed report of all its foibles and best way to proceed. From initial phone call to picking up car after, truly an exceptional experience. Thank you!!

 Trustindex verifies that the original source of the review is Google. Easy to tow in car. Called me and asked what the issue seemed to be and fixed the problem. They pushed an oil change and air filter change but was quite a bit overpriced. Over $300 for both. I understand they need to make money but be wary of that. Otherwise they did good and fast work.

 Trustindex verifies that the original source of the review is Google. Had a great experience and felt well informed about my F-150 EcoBoost repair options for a coolant leak that caused the engine to overheat. I wasn’t feeling my best while facing the consequences of my truck requiring major repairs. The detailed estimate broke down every cost, from clips and hoses to labor, so there were no surprises. My questions were welcomed, and they took the time to explain what to expect. The staff and management were friendly, knowledgeable, and genuinely helpful. I especially appreciated the straightforward, low-pressure approach compared with some of my past dealership experiences. Highly recommend!

 Trustindex verifies that the original source of the review is Google. I had to tow my vehicle into Tristar at 4pm the Friday before a holiday weekend. I was stranded in the side of the road and didn’t know who to call so, after a brief google search, I called Tristar.

They let me know I’d could have my car towed over and it could stay over the long weekend but that they’d get back to me with an update as quickly as possible upon return from the holiday. As promised they did get back to me and let me know that the situation with my car was something that was actually covered by the maker of my vehicle via a class action lawsuit / extended warranty fix (my car is 1.5 yrs out of manufacture warranty). They told me to go ahead and make an appt with a local dealership and let me know exactly what to ask for re: this extended warranty. Additionally, they didn’t charge me for the diagnostic time it took them to identify the situation.

I’m incredibly appreciative of their responsiveness and honesty in a moment that was very unexpected and stressful. They absolutely have my business from here out!

 Trustindex verifies that the original source of the review is Google. I have had a couple recent repairs here including the catalytic converter and brake booster on my ‘98 Tacoma. I’ve been impressed by how responsive, timely, knowledgeable and professional the shop owners are! Thank you for all the high quality work you guys have done! It is much appreciated even though the issues have been unanticipated. It’s been a pricey last six months for me with all the vehicle repairs, but I’m trying to keep it running well for at least another 100K miles. 👍🏻 I hope I don’t have to come in anytime soon… :)

 Trustindex verifies that the original source of the review is Google. My first experience was great! Ken was professional and fast. I needed a new catalytic converter in my 2014 Kia so it could pass the smog test - Ken was communicative and friendly. I love that they have a company Uber account so I could be taken home after I dropped my car off.

 Trustindex verifies that the original source of the review is Google. Ken & Zac got me in quickly, diagnosed my issues, and got me back on the road tootsweet - pardon my french. (They even laughed at my corny jokes!  Thanks, guys...😇)

My problem turned out to be much less serious than I thought, and they were in contact with me the through the entire process. AND they got me a rideshare to and from!

If you want a shop with friendly, reliable folks, you won't go wrong with  TriStar!

 Trustindex verifies that the original source of the review is Google. TriStar Automotive began with an oil change.  Most recently I received more service to my car.  It needed the attention and TriStar Automotive provided exceptional service.  I would highly recommend TriStar to anyone looking for quality, honesty, and integrity.

 Verified I needed to have my Exotic car's DMV exhaust certification renewed. The car is an 1988. I have quite a bit of angst when every two years the certification has to be renewed.
I took the car to TRISTAR. They were WONDERFUL!! They felt my concern. The car passed with flying colors, twice at this time!
The people who own/work at Tristar are master mechanics! They were kind enough to give me a referral for an excellent Exotic car repair shop. Since moving to Sonoma County eight years ago I have been in convulsions on where to take my car for engine repairs. Tristar's recommendation was another star on their rating. They should receive  10 stars!!!
