Gary was great to deal with.
Gary was great to deal with. Everyone at the dealership was nice honest and friendly. They didn’t try to up sell me on anything and the finance department was fast and honest.

Excellent experience purchasing my wife’s Ford Bronco
Excellent experience purchasing my wife’s Ford Bronco Sport. I insisted on the Badlands edition and she chose the color. Red McCombs was the only Ford dealer in town that had all the bells and whistles we wanted, in the right color and for a great price! Marwan Nsaif went above and beyond to help make this deal happen and followed up with us every step of the way, even picking up an accessory that wasn’t available at his dealership. Marwan is a true sales professional that you can be confident has a win-win solution for your next automobile purchase!

5 Stars – A Truly Exceptional Experience.
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.

Remarkable service!
I bought a 2023 Tundra TRD OR pickup this past weekend. I drove over 4 hours to make this purchase and everything from my first call to driving off the lot was remarkable! My salesman, Roger S was very personable and took the time to make sure everything was ready when I arrived. I was in and out in less than an hour and back on the road to head home. I would certainly purchase from them again. Great folks at San Marcos Toyota!

Seguin Chevrolet is the Best
This is my 2nd vehicle purchase from Seguin Chevrolet. I will continue to keep coming back here and especially to my salesman Arnold Guerra. He is the best and goes above and beyond for his customers. If anyone is in need for a vehicle come to Seguin Chevrolet and ask for Arnold Guerra. The whole Seguin Dealership treats you good and like family.
