I recently had the pleasure of working with Geno
I recently had the pleasure of working with Geno Hernandez while purchasing my new Yukon, and I couldn't be happier with the experience. From the very beginning, Geno took the time to understand my needs and helped guide me toward the right vehicle for my family. What really stood out was his commitment to customer service. The specific Yukon I wanted was located at another dealership, and Geno went above and beyond to make sure it was brought in so I could get exactly what I was looking for. Of course, none of that would have been possible without the support and approval of Mustafa. As a manager, Mustafa clearly leads by example and works closely with his sales team to ensure customers have a positive buying experience. His willingness to assist and help make the deal happen speaks volumes about his dedication to both his team and his customers. Let's be honest, buying a vehicle can be both exciting and stressful. There are a lot of decisions to make, and at the end of the day, the numbers have to make sense. What I appreciated most was that there was no pressure. Geno and Mustafa worked with me, answered my questions, and helped put together a deal that I felt comfortable with. If you're in the market for a vehicle, I highly recommend stopping by Classic GMC and asking for Geno Hernandez. The combination of excellent customer service, strong leadership from Mustafa, and a genuine commitment to customer satisfaction made this one of the best vehicle purchasing experiences I've had. Thank you, Geno and Mustafa, for going the extra mile and helping make the purchase of my Yukon a great experience!

Advertised a new 2025 Sierra 2500 for $41,845 on AutoTrader and their website. When I called ready to purchase, I was later told the price required trade-in and dealer financing incentives that were not clearly disclosed in the ad. After questioning the pricing, I was told the truck was suddenly sold moments later. Buyers should verify all pricing and rebate conditions before placing deposits. I do not recommend this place at all. Avoid it all costs.

From the moment I pulled into Classics Pre-owned parking
From the moment I pulled into Classics Pre-owned parking lot to the moment I drove away in my newly purchased 2020 Challenger R/T Black Top 50th Ed was hands down one of the best car buying experiences I've ever had. The sales staff, porters, finance, all of them went out if there way to make me and my friend feel welcome. They made sure we had something to drink, were comfortable, all while maintaining a courteous and professional environment. They were such a joy to work with. I noticed everyone at this dealership treated all who walked through their doors the same way. Kudos to fostering such positive culture. You're staff are all top notch. While there might be a couple of things on my car that might need attention, I can assure you, if I'm ever in the market for another vehicle used, or new, I will be making the two and a half hour drive from San Marcos to Houston to do business with Classic again.
