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
The Audi A6 sedan resides where luxury, performance, technology and sophistication meet. If that sounds like your sweet spot, start planning a test drive. If you’re looking for a high-performance alternative to a V8-powered BMW M550i or Mercedes-AMG E43, the S6 packs a wallop.
If you want your car to have instant recognition and vehicular validation, the BMW 5 Series and Mercedes-Benz E-Class are better known in this class. The Lexus GS, meanwhile, is predicted to have slightly higher resale value.
