Dealer Description

Recent Arrival! 2021 GMC Sierra 1500 SLT 3.0L I6 Cayenne Red Tintcoat. 10-Speed Automatic, 4WD, Jet Black Leather. We believe there is more to buying a vehicle than worrying about the price. For that reason, Key Auto has simplified that process for our customers. When we price a vehicle, we take the following into consideration: 1) market conditions, 2) what the area dealers are selling them for, 3) NADA retail value. This way, when you leave a Key Auto Dealership, you're confident you've received the absolute best deal.
