Hat ' s up to Davis and Ariel
In Today's seller market, the Davis staff did everything in their power to make our purchase of an Equinox as easy as possible as well as affordable as possible. I like the no pushy sale. They explained and let you decide. It helps to have salesmen who are experts in cars. and they do have those. I would pay them a visit for my next purchase, even if just to ask about a brand they dont carry. You will not regret it.
Beautiful truck
I love my 2021 GMC Denali 2500HD. I have gotten more complements on this truck than any other vehicle that I have owned. I get great highway fuel milage average 19-26mpg,which is great for a heavy duty truck!

Offsite remote Purchase with vehicle delivered.
Offsite remote Purchase with vehicle delivered. Transaction was flawless, the sales representative was on point and informative. Brian Crawford was the representative I dealt with, ask for him when shopping at Bowman Chevrolet.
Best truck I ever owned

Honest and very transparent.
Honest and very transparent. Everything was explained in detail and the staff was very friendly. Highly recommend Star for all your truck needs.
Early to tell truck has less than 100 miles
Truck was bought specifically to our travel trailer. We have to wait for 1000 break in before we can tow the trailer. So far the truck is very quiet, smooth running, & comfortable to drive. We were pleasantly surprised at how much interior storage space is available. Having the bed steps before rear tires and in the bumper sides is very nice. Bed rails are even with my shoulders so the steps get used a lot.

Great service
I found the best price on a Chevy Bolt with low miles. While the car wasn’t perfect, it was in good condition. The staff was friendly and attentive. Tony assisted us and made himself available by email and text, was very responsive and accommodating. No, they do not allow. Negotiation on their used car prices, but it wasn’t needed. The other reviews harping on that fact shoe the arrogance and entitlement some consumers have despite Their prices being more than fair. If a good product at a great price is delivered, why would you insult someone with a lower price? Have some respect. Only complaint was the cheap tires they put on the car. Horrible. But I expected a corner or two to be cut for the price I paid and for home delivery.

Hello GMC Team, On February 28, 2026, I posted a
Hello GMC Team, On February 28, 2026, I posted a review regarding my experience at Tustin GMC, specifically concerning the inclusion of add-ons during the purchase process. In my review, I shared that I felt pressured when I was informed that a protection package valued at $4,200 had to be included in order to move forward with the deal. Today, March 1, 2026, I received a call from Tustin GMC management apologizing for the miscommunication. They explained that it was not their intent to pressure me, and that the final price presented actually included an extended warranty rather than a mandatory protection package. I appreciate the clarification and the outreach from management. I accept their apology and want to acknowledge their effort to address the situation and make things right. This type of follow-up and accountability is what excellent customer service is all about. Thank you to the GMC team for taking the time to reach out. Your actions truly go a long way.

Due to a Module going bad on my 2022 truck I had it towed
Due to a Module going bad on my 2022 truck I had it towed to Cheap's on a late Saturday afternoon. I called the Service Dept. on Monday morning to tell them the issues. They got right on it and I received text messages as they were working on it. They had me back on the road quickly. They always treated you great. I depend on them for all my work. Great People Great Place!!

I did not end up purchasing a car with this dealership
I did not end up purchasing a car with this dealership however I did not because of the honesty of the dealership. The dealer fully disclosed prior damage the vehicle had and the repairs. It was my decision to not purchase because of the damage.

Purchased a used SUV from Lonnie today.
Purchased a used SUV from Lonnie today. We had an immediate connection & the overall experience was outstanding. No suits & ties here folks, just regular straight forward people. Never once felt pressured. Had the opportunity to go through the vehicle pretty extensively. The entire staff here is down to earth & understand what real service is. A refreshing experience to be on the receiving end of that small town hospitality!
