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
Professional yet premium attitude. Engines range from a turbo 4-cylinder to a 6-cylinder diesel and a big V8. Innovative hardware and technology to enhance work or play. Denali — the popular Sierra luxury version.
Doesn’t tow as much as the Ford F-150 and Ram 1500. Also lacks those rivals’ max payload rating. Not on the cutting edge of tech.
