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.

We had our truck towed into Hardin GMC for some major engine repairs. Shawn was our service writer and he communicated with us regularly and was clear about all the repairs needed. Once we approved the repairs, they were made nearly a week faster than expected. Overall we are extremely happy with the service we received.

Reynolds GMC review
The service staff were friendly and efficient. My car was serviced (oil changed and tires rotated) and ready in a timely manner. The waiting area and rest room were clean
2026 GMC Sierra 1500 review
A little expensive, but comfortable, quiet, smooth ride. Great performance out of the 6.2L and better than expected fuel economy in the low 20s. Outstanding interior and good looking exterior, especially in the Downpour Metallic color. I don’t have 700 miles on it yet and have owned it for 3 weeks. Therefore, I can’t pass judgement yet on the reliability, but so far I am very satisfied. This replaced an 8 year old Ford F150 that served me quite well with only a couple of issues in the 100,000 plus miles.

Professional and superb customer service. Was dealing with a check engine light. They go out the way to make sure customer is taken care off.
2026 GMC Sierra 1500 review
I bought the AT 4 version. Loaded. Has good ground clearance. It's powered with a 3.0 l turbocharged diesel. Has lots of horsepower and torque. I've had no problem but I talked to my friend who's a certified mechanic and they're having a lot of problems with the engine blowing up at very low mileage. A lot of the time less than 15,000. Some of them have problems with the thrust bearings failing causing increased crankshaft play back and forth to the point where the timing chain and the rubber belt that runs the oil pump can fail. The engine has been described as grenading. They're basically self-destructs. There's a specific power code that indicates low oil pressure and allowed rattle sound before it finally fails. I heard that the engines were on back order, so if you're one of the unfortunates you can plan on waiting 10 or 12 weeks or longer to get your truck back. They have to remove the cab completely to swap motors. But overall I love the truck. It's a big improvement over the 2022 I just traded in.

I called the dealership and spoke to Gary Koch. I found him to be very personable and knowledgeable. We discussed the online price and agreed to purchase the car. I am not local and handled the preliminary paperwork over the phone. Once everything was confirmed I booked a flight and Gary offered to pick me up. I was in and out of the dealership in less than 90 minutes. Gary made the car buying process super easy and enjoyable. I also received an exceptional deal.

On April 6, 2023, I took delivery of a 2023 Yukon Denali Ultimate, which was a SUV that I ordered, equipped the way I wanted it. John and the entire sales staff were great! I have purchased/leased 4 other vehicles from this dealership and have always been treated well. If you want to avoid all of the seemingly normal drama that goes along with walking into a dealership, you need to try this one - you'll be pleasantly surprised.

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.
