New and used 2026 GMC Sierra 2500 AT4 trucks for sale near Fresno, TX

I want to say I have been coming to this location for over 20+ years & the day I brought my truck in for service, I was not able to get taken care of & had to go elsewhere to get my truck worked on. I was asked for a review which I gave expressing I was unhappy about my experience. A few days later I got a response from David Marti Jr who asked I contact him to find a resolution & I did. Let me tell you, David took control of the situation & provided me with excellent service & kept in contact with me during the process. It was refreshing to have someone step up & provide good old school service & kept on it until it was done. I hope Group Auto takes care of him because he's the kind of guy you can build your business around & keep folks coming back. I was very Pleased with Mr. Marti's efforts & professionalism. I will certainly be back as a customer. Thanks Danny Maeker

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!!!

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.

Honestly the BEST car buying experience we have ever had:) I highly recommend Gay Family Auto Trey, Kiss and Steve are amazing. From the time we walked in to the day that Trey delivered my sons truck it was ABSOLUTELY PROFESSIONAL.

I received excellent service from everyone who helped with my car purchase. Everyone worked hard to make sure that I was satisfied with my purchase, and I really appreciate the patience and helpfulness that I was shown.

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.

As always everyone treats me as if I am Family! Great people and great service They make the experience a good one Every time all the time.

Professional and polite was greeted upfront from the beginning. Work was done quick. Great job

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.

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

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.
