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
With prodigious power, advanced technology, and luxurious surroundings, the 2015 BMW 6 Series offers a surprising value compared to competition like the Jaguar XK and Mercedes-Benz E-Class Coupe.
Of course, "value" is relative, as the base price of a BMW 6 Series is more than $75,000. If that’s too dear for you, the Audi S5 offers a quick package at a considerably lower price. BMW’s own 4 Series coupe does the same, and keeps that coveted badge.
