I went and purchased a used Telluride on 9/4. Harold the salesman had been working with me the day before and worked countless hours back and forth giving me information I needed, and working on Harold the salesman had been working with me the day before and worked countless hours back and forth giving me information I needed, and working on his end to get me a great price. When we reached the agreed price, I showed up the next day and the process was seamless and smooth. They gave me a great deal on my trade in, better than all the other dealers I tried. Harold was very professional and polite, and so were his team that assisted. This was the best car buying experience I've ever had, and they will definitely be remembered on my next purchase. Ask for Harold when you check out this location and you won't be disappointed. More
