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
If the $85,000 base price of a 2015 Mercedes-Benz SL400 doesn’t scare you off, you’ll love the power, cutting- edge technology, impeccable craftsmanship and prestige of owning one of the most iconic Mercedes-Benz 2-seaters ever built. What else do you need?
As beautiful and prestigious as the Mercedes-Benz SL-Class is, you’ll get more performance out of a Porsche 911 or the new Jaguar F-Type. Neither can match the raw horsepower of the SL65 AMG and its V12 engine, but they’re much better driver’s cars overall.
