Why would you go anywhere else? Brett is absolutely fantastic, he's down to Earth and truly wants to find you a perfect fit vehicle. Tim is 10/10. He goes above and beyond discussing financing and ended up making my dream car a reality. Whitlock Motors is the best local dealership you could find. If you want the best car buying experience, there is no where else to look. Try Whitock. Their name really does mean a great deal.
