New and used 2026 GMC Sierra 2500 Denali Ultimate trucks for sale near Jacinto City, TX

Got my truck serviced with no trouble. Omar was very informative and had amazing customer service from the second I arrived to check out time. Great guy.

Great service from Mrs Hernandez, very nice and friendly and knowledgeable she explained everything to me. The process was smooth and swift. Definitely my favorite dealership.

Buying experience was good and the Finance department was excellent. Thanks for the no hassle experience. It was my first visit to the location and I would recommend it to other buyers.

Thank you group 1 south GMC, Pepe and Angel were great. 3rd vehicle from them. Happy Christmas 🎁⛄.

Khanh Vu was very informative and helpful. Exemplary customer service! Explained in detail all the issues that I needed to address. I waited for my service and it was completed earlier than promised. Thank you, Linda G

I want to take a moment to recognize Anthony Alvarez at Group 1 GMC Buick South for an outstanding car-buying experience. I came into this process already approved and funded through my personal bank, fully prepared to purchase a 2024 Ram Laramie elsewhere. Unfortunately, the lack of professionalism at that dealership led me to walk away at the last minute. Walking into Group 1 GMC Buick South was a breath of fresh air. Anthony immediately stood out ? not as a typical salesman, but as a genuine, respectful, and knowledgeable professional. Anthony is a former Marine, and as a Navy veteran myself, there was an immediate sense of mutual respect and straight-forward communication. He was down-to-earth, transparent, and never once applied pressure. He listened to what I wanted and helped guide me to the right decision based on my needs ? not just the sale. Because of Anthony?s professionalism and integrity, I confidently purchased a 2023 GMC Canyon, and I couldn?t be happier with my decision. In an industry where honest salespeople are hard to find, Anthony is truly the real deal. If you?re looking for someone who treats you with respect, communicates clearly, and genuinely cares about doing right by the customer, ask for Anthony Alvarez. Group 1 GMC Buick South is lucky to have him.

Thank you, Group 1 Buick GMC South team, for providing such a great purchase experience. Your team truly knew how to handle an internet purchase with professionalism and ease.

Great, Vickie?s the best service writer that I have ever had. The dealership looks after their customers, and makes sure they are satisfied with the results of the repaired vehicle.

Good customer service. They sent me new blades to replace the old ones and even offered to install them for free. Thank you for your generosity

I would definitely purchase my next car from classic ? the staff was friendly and they really help me make a purchase on the right car

Professional service! I am content with the work. Site is in busy business. The advisor was also in full schedule, but I was good for the time waiting.

This place had great energy took there time to satisfy me of what I needed and Steven was amazing would definitely recommend this gmc dealership

Enjoyable experience in and out knowledgeable salesman the guy who handled my financing was great they made it seem very easy I would definitely recommend it to friends and family, which I already have.

The guys where straight forward and even drive the car home for me as it was late and dealership was already closed by the time we where all set and I came with my second car

Very disappointed that Sterling McCall doesn't honor the $49.95 price they advertise on their website. This is the second time this has happened. Why even advertise if they don't honor.

All aspects of the car buying process were amazing. Truly a high class business, next car will be bought at this car dealership, truly top of the line!!!
