Annual Depreciation is an estimation of what your vehicle's value might be over time based on an average of similar vehicles. 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.

KBB.com Review
Kbb.com Expert Rating
Opt for the big 6.2-liter V8 and the right configuration and you’ll get a class-leading 12,500-pound tow rating. The Toyota Tundra can’t match the Sierra’s horsepower and doesn’t offer upscale features like ventilated front seats or adaptive suspension.
If you’re seeking a diesel or turbocharged engine in your next half-ton pickup, the 2018 GMC Sierra is off the list. You can get a diesel in the smaller GMC Canyon, a less expensive option that nearly matches some of the Sierra’s bed and payload figures.
