What Our Clients Say:

I was very impressed with GM Experts. I am from Idaho visiting family in town when I found my Air Ride Shocks were shot and brakes were bad. They were able to get me in on New Years Eve and have it done same day so we could head out early the following day. Their pricing was best in the valley and I called a lot of folks. I would highly recommend GM Experts. They were fast, good service, and rates could not be challenged.

I was referred to GM Experts by another shop attempting to “heal” my “new to me” C6 Vette. While it was the last thing I wanted to do, (basically rebuild engine) I made the major investment. I couldn’t be happier so far taking it to this shop where you’ll find a solid team that provides quality work at a reasonable price! Thanks Cory, Brian, and Jeremy for “healing” my manual C6, where I hope to have years of enjoyment/fun with an additional 70HP-100HP!!!

How have I not reviewed this place? About a year back I had to replace an engine in my 2011 Equinox and these guys took care of me big time. They worked with my warranty company to just about eliminate my out of pocket and today they helped me again. Brian worked with this same warranty place to ensure my AC unit was replaced and working properly going forward. I appreciate these guys and always recommend them to family and friends. Go here and support honest mechanics with an attention to detail!

These guys know their stuff. Particularly attentive to the details, especially those smaller details that often go unnoticed and typically lead to bigger issues down the road. They treated my '01 DeVille like it was their own. Highly recommended.

Thanks for honest and quick work to get the A/C working on my GMC truck. The cost for the repairs was much less than I expected. Brian was professional, responsive, and diligent. I was referred to GM Experts by a friend and they did NOT disappoint. I will definitely be referring them to other friends in the future. Thank you sirs.

The A/C went out in my Hummer H2, I googled GM repair shops and GM Experts popped up. I made the appointment and also mentioned to them that the prior mechanic I was taking my Hummer to had mentioned the Hummer had a Rear Main Seal Oil Leak and it needed fixed for a lot of money. I told GM Experts about it and they said they would check it out. GM Experts by far exceeded my expectations, not only is the A/C blowing stronger than it ever has but come to find out; the Rear Main Seal wasn't leaking at all. The prior mechanic shop I was taking it to was just trying to rip me off by adding oil in the engine to make it look like oil was leaking. If GM Experts was a dishonest company, they could have easily taken advantage of me; but they didn't. Finding an honest mechanic in this world is like finding a needle in a haystack, I am happy to say I have found that needle in a haystack; GM Experts is my #1 choice for a mechanic.

Great folks. Good honest repairs for my GM car. They charge a very reasonable diagnostic fee. Had to take my door apart to get to my electric window. Fixed unit perfectly and guaranteed their work! Communicated with me so I could understand what the problem was and exactly what was needed to fix it.
