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 2009 Mercedes-Benz SL is more than just a performance dynamo; it’s an attention grabber. The car looks as good with the power-operated hardtop covering the cockpit as it does when retracted. If you believe a car’s first mission is to convey your success to the world, then the SL is the ideal spokesperson.
The only reason not to like the 2009 Mercedes-Benz SL is the price. Don’t feel bad; well over 90 percent of the rest of us can’t afford one, either.
