2-Year Forecasted Depreciation
*Depreciation for the last 12 months of the private party resale value.
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.

If you’ve grown perfectly comfortable in the lap of luxury but occasionally miss the fun you used to have in a BMW 3 Series, you may find happiness in the 2009 Audi S8.
If one of the reasons you’re looking to drop some $100,000 on your personal transportation is for the attention that often accompanies such a move, the S8 might be a little too visually understated for your liking.
