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.

Alex G is probably the most helpful car salesman there
Alex G is probably the most helpful car salesman there is. Not only did he make sure to really do everything he could to get me a great deal on a car I actually wanted, but as a first time car buyer no other dealership or car salesman wanted to seriously help me, but he did. I can’t recommend Alex enough at this dealership.
