The 2004 GMC Yukon XL, part of GMC's full-size SUV lineup, fits squarely in the third-generation of Yukon models. This classic American SUV comes in RWD or available 4WD, paired with a 4-speed automatic transmission. The Yukon XL offers two engine types: the standard 5.3-liter V8 producing 295 horsepower or the beefier 8.1-Liter V8 putting out 320 horsepower. The model comes in three different trims - SLT, SLE and Denali, the last of which takes a more luxurious approach with upgraded finishes and technology. Safety features include an anti-lock braking system (ABS) and dual frontal airbags. Though infotainment systems were less developed during this era, the Yukon XL boasted a CD Player and optional DVD Entertainment System. Despite its age, the 2004 Yukon XL continues to be appreciated for its roomy interior, smooth ride, and solid towing capacity.
