2026 GMC Sierra 1500 AT4X review
A little expensive, but comfortable, quiet, smooth ride.
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.

Tustin Buick GMC review
I had an amazing experience yesterday at Tustin GMC &
I had an amazing experience yesterday at Tustin GMC & Buick with Seth R.. I called him the night before to ask about the Sierra EV 2025, and he got right on it! We got the deal done in minutes, charged up the truck, and it was waiting for me to pick it up the next morning because I couldn?t make it that evening. This dealership is incredible! I usually buy luxury vehicles, and the service was just as great as when I do business with Porsche or Land Rover. George in finance was nothing short of amazing as well. The management is doing an incredible job keeping them going because they have such a great team. Every turn was met with a smile, and even in workout clothing, I felt like a valued customer. Thanks to Seth and George, this dealership is now my new pick-up truck home, and I?ll definitely be buying my pick-up trucks through Tustin GMC & Buick in the future.

The prices attracted me. The customer service and experience/ level of knowledge was not great. There was an inconsistency of dealership policy. It would be nice to get a car for the price you expect. I felt forced to purchase items I did not want
