Tustin Buick GMC review
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.

I’ve been in the market for a Huracan for a while. The guys at ECF came thru big time with a beautiful spec. The process was easy and the team was incredibly pleasant to work with. I hate the car buying experience, but these guys know how to do it right without a doubt. Would recommend to anyone!

Mark Christopher GMC is an amazing Auto dealership. No sales pressure and terrible prices. Johnathon Villa was an outstanding salesman that helped us get a 2022 Canyon Elevation. He took extra steps to help us find the perfect truck for us. We drove over an hour. And so glad we did. Highly recommend. And I want to say thanks again to Johnathon for making the experience great.

Mark Christopher Chevrolet Buick GMC Cadillac review
Alex was a pleasure to work with throughout the process. When I expressed my concerns about covid he kindly agreed to wear a mask and arranged for the process to be conducted outdoors as much as possible. He also expedited the sale process because he understood that I needed to drive the vehicle back to the SF Bay Area that day. Lastly, he was very knowledgeable about the Suburban that I purchased, and provided me with a lot of great information about its features and benefits. I wouldn't hesitate to work with Alex again, or to recommend him to others.
