Saw an 03 GMC Sierra diesel for sale that I sell trux had, gave them a call an Adrian answered the phone. Right from the start he was very professional.... I called him quite a few times on this truck and he always had an answer for me. A lot of dealers sell diesels and are clueless about them, Adrian knew about the truck and wasn't just repeating something he read. When I went out to see the truck it was exactly as he described, there was no bs over the phone about how great it was. I did a credit app ahead of time with him so when I purchased it credit was all set. After coming back from a test drive I noticed the temp gauge wasn't working, I said to Adrian give me fifty dollars back and I'll take care of the problem myself (my stepson is a mechanic and it wasn't a safety issue). Adrian said if I didn't need the truck right away he would fix the problem and deliver the truck to me. Sure enough, two days later the're in my drive way, I live 65 miles from the dealership. Can't say enough, very happy with my purchase.
