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
This truck was built to help you tow heavy things on a daily basis, whether it’s short or long distances. Whatever the job calls for, the 2015 GMC Sierra will get it done.
There’s not a whole lot of daylight between the Sierra and its more mainstream heavy-duty truck cousin, the Silverado. Like the Silverado, the Sierra HD doesn’t lead the class in towing numbers, either.
