Ross Downing GMC Cadillac review

Our salesman, Landon Crane, is new and even didn’t have

Our salesman, Landon Crane, is new and even didn’t have his business cards yet but he’s gonna go far. He was extremely polite, willing to answer questions and had no problem getting up to ask about an answer he wasn’t certain of. I appreciated he wasn’t pushy, condescending, or fake. He may be young and just getting started but you won’t go wrong by requesting him for your salesman. The young man knows how to give an appropriate handshake on top of all his other positive qualities. From start to finish it was a relaxed buying experience. Give him a call!
