2020 Mercedes-Benz SL SL 550 Roadster 2D Depreciation
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.

2020 Mercedes-Benz SL
KBB.com Review
Power, poise & performance in equal measure. Comfortable & luxurious cabin. Power-retractable hardtop roof. Power wind-blocker and Airscarf neck warming. Heated, ventilated, massaging seats w/sun-reflective leather.
Imminent replacement by a much improved, AMG-engineered example. Sky-high prices for a vehicle that will depreciate rapidly.
