Great dealer.
Great dealer. I bought a new truck from them after I got a new truck with a lot of issues from a different dealer. I took that truck here for service and they were amazing! They gave me loaners even though I did not buy it there and did everything that they could to help. So I bought a new truck from them because of that.
Nicest, best performing truck I've ever owned
My truck has a great appearance, inside and out. It is a pleasure to drive; and rides and performs great. It is the best truck I've ever owned.

Needed a car door.
The salesman did a great job and even though I didn't buy the car I was interested in, it was because the salesman had the integrity not to sell it to me as soon as he learned there was a transmission issue with it. The honesty was refreshing.
There are 20 matching cars close to your year range.
