Great dealership
Very friendly people and great to work with. They found a way to get me approved without any issues. Definitely recommend if in need of a vehicle.
Great Truck
I paid over $106,000 for this truck with warranty. Do not care much about miles per gal. at that that price range. Just too much truck for me at my age.

True customer service
I wanted to purchase a new vehicle and Terry was the sales man who also sold my mom a car his kindness and understanding made me me feel comfortable. His customer service was spectacular. The finance person was also so kind. I will recommend this dealership to others. They know how to make their customers feel valued.
Great Truck (sans MPG)
Love everything about this Duramax Denali except the fuel mileage. 13-14 Mpg tops when not towing. Bought truck cause previous was stolen. Wish I still had my 6.2 High Country!
