My son and I recently visited Tustin Buick GMC to purchase a used vehicle. We were greeted by Josh and Guneet who assisted us. Both Josh and Guneet were extremely professional and personable. We were able to negotiate a great deal with a no nonsense approach. I would highly recommend them and the dealership to all my friends and family. Wyatt H.

Avoid Tustin Buick GMC if you expect integrity,
Avoid Tustin Buick GMC if you expect integrity, transparency, or even basic customer service. I purchased a used Porsche 911 Turbo from them in November, and within days the check engine light came on, revealing an ignition system failure that directly affects smog compliance. This essentially means the dealership’s “passed” smog check was invalid from the start. When I brought this up, they initially refused to take responsibility — until I mentioned California Lemon Law protections. Only then did they agree to begin the process of fixing the issue. From that point forward, I encountered horrible customer service, deflection, and a complete lack of professionalism. I was treated like the problem — not someone who just wanted the vehicle they paid for to function properly. I had to spend my own money on rides and parts while they dragged their feet. One time, they had me sit at the dealership for over 7 hours, did absolutely nothing to the car, and didn’t even offer me a ride home. It wasn’t until April — 5 months later — that I finally had a car I could drive without a check engine light on. Even then, new problems have continued to surface, including a recent oil leak and prior pulley failures, all of which point to pre-existing issues. Despite repeated attempts, I still have not been provided paperwork or documentation for the repairs they performed. If you’re thinking of buying from Tustin GMC — don’t. Their behavior after the sale is disrespectful, slow, and negligent. You might get a car, but you won’t get any support, accountability, or peace of mind.
