"Drove the truck for 3 days with the stock 17inch wheels before The dealership put the 20" wheels I added on. Huge difference! 20" wheel/tires made it feel like a sports car. Super comfortable truck. MPG is better than the 2002 V6 I traded in. Like the electronic trans temp guage and tire pressure sensor and of course the Automatic headlights. You cant go wrong with a New Chevrolet."
