We are Big Star Buick GMC. You might expect a car company’s top priority to be cars, but not at Big Star Buick GMC. To us, people are number one (though cars are still a close second). That’s why our favorite three words are We Hear You. They say so much without us having to say much at all. When we listen to our customers and put their needs first, quality vehicle selection, fair prices, reliable service, and a welcoming environment are all a given.

We purchased two vehicles from Big Star Buick GMC within days of each other, a new 1500 Sierra Denali and a used Yukon XL Denali, a significant investment made in good faith, especially with a baby on the w days of each other, a new 1500 Sierra Denali and a used Yukon XL Denali, a significant investment made in good faith, especially with a baby on the way. What followed was one of the most mismanaged and dishonest buying experiences I have ever encountered. The problems started immediately. The Yukon XL was delivered with a rusted tire imprint on the leather seat, caused by a tire that had been stored inside the car. We were told it would be removed. When we came back to pick up the car, it was still there. We later learned from our own detailer that the damage was permanent, something the dealership almost certainly already knew. Because the trade-in paperwork was not processed in a timely manner, we were forced to make double payments, covering both the new vehicle and the old one simultaneously. That cost us real money due to their administrative failure. When the Yukon XL was presented to us, the brake system was actively alerting that the vehicle needed service. Our sales rep Mike claimed it had been taken back and fixed. It had not been fixed. The alert had simply been disabled. When I called this out, Mike issued a "we owe" document acknowledging the brake system still needs proper service. That document has yet to be presented or honored. We were also promised a second key for the Yukon XL. The dealership's own buyer confirmed there was a second key with the previous seller and that they were in the process of obtaining it for us. Two months later, I followed up and Mike walked back the entire commitment, claiming he had only promised to "locate" a key, not actually deliver one. We have text messages that tell a different story. To summarize: we are still without a second key, and we are still waiting for Big Star Buick GMC to honor their own written commitment so our vehicle can be properly serviced. Both remain unresolved. What appeared to be a good deal turned out to be a series of half-truths, deferred problems, and broken promises. If you are looking for a straightforward, honest car buying experience, look elsewhere. More

I purchased a 2024 GMC Sierra 3500 Denali Ultimate Dually from Big Star Buick GMC in Baytown, Texas on March 12, 2026 for $95,000, including extended warranties and GAP coverage. The salesman represented the from Big Star Buick GMC in Baytown, Texas on March 12, 2026 for $95,000, including extended warranties and GAP coverage. The salesman represented the truck as clean with no accidents, and the price also reflected this. While driving the truck back to Colorado, the trailer brakes and blind spot sensors were not working. A Denver GMC dealer discovered significant rear-end accident damage, weld marks, and body repair that was never disclosed to me. When I contacted the dealership, they were condescending and smug. They refused to negotiate a settlement in good faith and simply told me they would take the truck back with no compensation. This is blatant deceptive practice. Do not buy from this dealership. More

The price listed on the website is not the actual price when there is any aftermarket items added to the vehicle. Despite showing the alterations to the vehicle, the price listed is the original price. I d when there is any aftermarket items added to the vehicle. Despite showing the alterations to the vehicle, the price listed is the original price. I drove over 6 hours to purchase a truck that I called the dealer about. Not until after looking at the truck and saying that I was ready to buy did the salesman say that the aftermarket items aren’t included in the price on the site. May not be illegal but sure is “tricky” advertising. More

The buying experience I received from Alex made my trip a pleasure coming from Louisiana and he really took the time and care needed to make my truck all that I wanted and expected. I would definitely recomm pleasure coming from Louisiana and he really took the time and care needed to make my truck all that I wanted and expected. I would definitely recommend buying your next vehicle from Alex and the Big Star family. More
