***ONE OWNER*** The 2010 Cadillac Escalade EXT is essentially a premium full-size crew cab pickup truck that's available in three trim levels: base, Luxury and Premium. Standard features on the base version include 18-inch alloy wheels, xenon headlights, a roof rack, a road-sensing adaptive suspension, a fold-down midgate, power-adjustable heated front seats, driver memory settings, power-adjustable pedals, rear park assist (with rearview camera), leather upholstery, wood-grain trim, dual-zone automatic climate control, remote engine start, OnStar and Bluetooth. Also standard are a navigation system with real-time traffic updates and an eight-speaker Bose surround-sound audio system (with a CD/DVD/MP3 player, satellite radio and a USB port). Stepping up to the Luxury trim adds auto-dimming high-beams, 22-inch chrome-clad wheels, an automatically adjusting (Magnetic Ride Control) suspension, a sunroof and a heated steering wheel. The top-of-the-line Premium adds power-retracting side steps and a rear-seat entertainment system. A few of the upper trim features, such as the Magnetic Ride Control suspension and the DVD entertainment system, are available on the base model.
