Great follow up scheduling went perfect.
Great follow up scheduling went perfect. Repairs were done quickly and it looks awesome.
I have the 1500 double cab with standard bed.
I have the 1500 double cab with standard bed. The reason I have this vehicle is I really like the 6.5 foot bed. The crew cab with same bed is just too long. The things I dislike about this model is that it only comes in the SLE model. For the 2025 that means the external mirrors do NOT have a power fold in and it does not have a seat memory for more that one driver. The power fold in for the mirrors is extremely important to me.

I purchased a 2025 GMC that was used which was listed online. I got an immediate response when I texted and they were very helpful in providing information. I feel I got a good deal. They handled getting the vehicle shipped to NC. I’d highly recommend Crown and Brandy (sales).

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.

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!
