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
If you think smaller and lighter cars tend to be the most fun, we think you’ll like the 2008 BMW 1 Series Convertible. It features a quiet, well insulated top and excellent top-down air-flow management, freeing it from the vices that commonly plague convertibles.
You may not like the BMW 1 Series Convertible if you want both front and rear passengers to be equally comfortable, as the rear seats border on claustrophobic.
