Single-owner Arizona history and 34,000 miles accompany this Summit White Yukon XL Denali. Its 6.0-liter Vortec V8 sends power through a four-speed automatic transmission to all four wheels, with AutoRide suspension and Michelin Defender tires on 17-inch alloy wheels. The Carfax report shows no accidents or other damage. Annual mileage sits near the low end for this generation.
