New and used 2026 GMC Sierra 1500 Denali trucks for sale near Carson, CA

Ok so I am sure my 1st review is not gonna be deleted but I have a new review for them as they have addressed my concerns and Because of 1 persons actions I am completely satisfied with the repairs and commitment that JOHN in service has made sure I was completely satisfied with the repairs so a big THANK YOU to John and anyone else who worked on this I will definitely be taking my truck back for service

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.

Victoria Gia and her sales manager did an excellent job of helping us without being too pushy. They stayed late after the dealership was closed to help us.

It was such a good truck honstly the greatest thing I have ever drove in my entire life I am so happy that I have been blessed with this being my first ever car

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

I went in to have an oil change, Oil change was completed in a timely manner. I waited in the waiting room which was very clean . My vehicle was washed , very good customer service

Great experience. Simple and easy. Great staff. Definitely would recommend.

I have 2 vehicles within 2 years from same dealership. no mark up like other shaddy dealership and not to push of the stuff that you are not comfortable. Highly recomend this compare to other price gauging dealership. As usual my service advisor josh is amazing and never push for anything that is not needed.

Experience was excellent! Everything was so smooth and easy! We are so happy with our purchase! Highly recommend Danny from GMC! Customer service was on point!
