Looks great but a little pricey for the year. Even though it has low mileage. I would buy a newer truck.

The GMC 2500 HD is the truck for me. Like all the other major brands of trucks the price is in the same range. The diesel engine and 4x4 is about good as it gets. For work or play GMC is the way!!
