Amazing experience!
Amazing experience! Everything was transparent no surprises, was worried about the long drive and having the dealership change things up on me but no everything was perfect. My sales man really is a down to earth gentleman, he went above and beyond for me and really hit a personal level of trust! Kimble wright is a name I will never forget based on my experience at this dealership.
