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 you’re looking for a luxury-performance convertible or 4-door coupe with a proven track record, the 2018 BMW 6 Series cars deserve consideration. The 6 Series is more reasonably priced than some European competitors, yet despite its age, can still run circles around many of them.
BMW’s 2018 6 Series doesn’t offer anything you can’t find in newer, less expensive BMW 4 Series convertible, Audi S5 or Lexus RC F Sport. Those needing a modicum of rear-seat room won’t find it in the 6 Series Convertible.
