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.

The 2008 Mercedes-Benz S-Class offers its owners a masterful vehicle. Drivers will enjoy the smooth powertrain and taut handling. Passengers will appreciate the first-class legroom and sumptuous creature comforts. The question becomes: Is it better to drive, or to be driven?
This is a big car in all respects—particularly the rear seat and trunk areas. If you don’t regularly carry passengers in back (or don’t plan on spending much time there yourself), you’re carrying around a lot of surplus sheet metal in an S-Class sedan.
