Five-Star Experience ?
Five-Star Experience ? A Memorable First Sale for Ryan! I recently visited the dealership to return my lease and explore the option of purchasing a new vehicle ? specifically a Chevy Tahoe RST. From the moment we arrived, Ryan, our sales consultant, was incredibly helpful and patient. We later learned this was his very first sale, and based on our experience, I?m confident it?s the first of many successful ones to come. Ryan, along with his supervisor Gabril, took the time to answer all our questions and made us feel comfortable throughout the entire process. We initially test drove a certified pre-owned Tahoe in pristine condition, and while it was impressive, I wasn?t sure buying used was the right move for us since we were transitioning away from leasing. As I was preparing to leave, I mentioned that I really wanted a new Tahoe RST in a specific model and color, which unfortunately wasn?t available on the lot. That?s when Ryan asked us to wait just a few minutes so he could check the latest inventory. Turns out a truck had just rolled in carrying the 2026 models of Tahoes and Suburbans ? including several RSTs! To make a long story short, my wife and I ended up purchasing a brand new 2026 Suburban RST with just one mile on it ? fresh off the truck. We couldn?t be happier with the vehicle or the outstanding service we received. Ryan and Gabril were professional, courteous, and genuinely invested in helping us find the right vehicle. We're thrilled with our new Suburban and proud to have been Ryan's first sale. Thanks again to both Ryan and Gabril for making this a memorable and positive experience!
This truck has a jerk when changing gears sometimes.

Very Helpful
Went to this Carmax off of an advertised vehicle. Vehcile was as advertised with no hidden charges or add-ons. We wanted to look at others and the salesperson walked us through all available vehicles. We ended up wanting to see one at another Carmax They set up arrangeents and we went to the other Carmax and purchased that vehicle. Both dealerships were very helpful and courteous. Price was better than other dealerships and there was no haggling. Actually a very easy buying process. I have not found a better price at ay other dealership in the area.
