Estimations are calculated by comparing Kelley Blue Book Private Party Values of vehicles similar to yours over time, as well as forecasts from Manheim Auction data comparing current and projected auction values against current Kelley Blue Book Private Party and Trade-In Values. This is not a guarantee of actual depreciation. Local weather conditions, market factors and driver performance will also impact your vehicle's actual depreciation.

2018 GMC Yukon XL Denali Sport Utility 4D Standard Features
2018 GMC Yukon XL
KBB.com Review
Kbb.com Expert Rating
If size does matter you’ll like the 2018 GMC Yukon. It’s big. And the Yukon XL is even bigger, providing interior volume and cargo space that make the Nissan Armada and Toyota Sequoia look like little hatchbacks. It’s also handsome, luxurious and its features list reads like a luxury car’s.
If you just need a people-mover with seating for seven or eight passengers, there are more fuel-efficient and less gargantuan SUV options out there like the popular Honda Pilot, Mazda CX-9 and GMC’s own Acadia. The Yukon also costs more than the very similar Chevy Tahoe and Suburban.
