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
If your next heavy-duty pickup needs to be as sophisticated as it is competent, the 2018 GMC Sierra HD has the power and technology to tow and haul like a champ. Denali models offer unsurpassed levels of luxury, while the All Terrain X model is the most off-road-capable Sierra to date.
A number of half-tons now offer an oil-burner under the hood, including the Ram 1500 and Nissan Titan XD. The midsize Chevy Colorado and GMC Canyon are also options. If you need maximum towing, you’ll find better numbers from the heavy-duty F-Series and Ram trucks.
