Hassle-free buying and excellent customer service. Best online shopping experience. Transparent pricing. San Antonio Buick GMC is the BEST!

So far so good! This truck is the nicest truck I have ever driven. The stance, ride comfort and options are top notch. I went from a 2023 High Country that was having drive train issues but had all the creature comforts that you would expect in a top of the line truck. With the lack of confidence in that particular models 10 speed transmission issues, it became necessary to reestablish my confidence in my General Motors product.

It was very professional and the sales person David Hill was very friendly and helpful. He's very good at helping me understand the process. It great place.

Great experience! Salesman Nate, was superior! We are very pleased with our purchase! Many thanks to Ancira!

Great service, as always!! Purchased from Ancira and all service work has been done here. I have recommended this dealership to all my friends and family and several have purchased from here.

Joseph always does a great job! Everyone here goes out of their way to make things so easy. That?s why we love coming here.

Since buying my 1500 Sierra in November 2021 during the chip shortage from a different dealer 4 hours from my house, I've always taken it to Ancira GMC in Boerne. At 119,000 miles now, it runs great, and I have to give credit to the guys there for being great at what they do.

I was really impressed with the service I received. As soon as i drove up, there was someone to greet me and they immediately did some testing. I was assigned ONE specific person to work with and that person was available to answer questions via text or phone. They even paid for an Uber to take me home!

5 Stars – A Truly Exceptional Experience. I had been searching across Texas for weeks, looking for a specific Yukon in a certain trim that was clearly in high demand—only ten or so were available statewide. Most dealers I contacted were either marking up the price well over MSRP and/or adding thousands in unnecessary extras. Then I came across the exact model and trim I wanted on GMC’s website, which showed it was in transit to Cavender GMC West. From there, the experience couldn’t have been smoother. I quickly found the vehicle on Cavender’s website and submitted an online price request. I got an instant response—and to my surprise (and Cavender's credit), they were offering the vehicle below MSRP with no dealer add-ons. A few minutes later, I received a call from Brandon Guzman. He confirmed the price without hesitation. No games, no changes—just total transparency. I asked if I could put down a deposit to hold the vehicle, and Brandon made it happen that evening. Over the next ten days, while I waited for it to arrive, Brandon stayed in touch. As soon as it landed, he called to let me know it would be ready the next day. I drove down from Austin to San Antonio, and when I arrived, the vehicle was freshly detailed, fully gassed up, and waiting for me to take it home. The paperwork took less than 40 minutes. No upselling. No pressure. Just a smooth, easy transaction. Brandon took the time to walk me through all the vehicle’s features and answered every question I had. I was back on the road within an hour and twenty minutes. He even texted me the next day just to check in, make sure everything went well on the drive back, and confirm that I had everything set up the way I wanted. I’ve purchased nine vehicles from seven different dealerships in my lifetime—this was easily one of the best buying experiences I’ve had. Brandon Guzman was honest, responsive, and incredibly easy to work with. Cavender GMC West runs a professional, customer-focused operation from start to finish. I’ll be back when it’s time for my next GMC—no question about it.

David Collins is great! I have nothing but respect for him. He?s honest with the whole process, regarding repairs. I wouldn?t want to work with anyone else.

Josue from Cavender in San Antonio was the sales agent helping me on my transaction, I live out of San Antonio however he did everything he could to get me all the info needed , pictures of my vehicle and even videos! I?m very happy with the outcome and I strongly recommend him for future purchases!
