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.

2018 BMW 4 Series 430i xDrive Convertible 2D Standard Features
2018 BMW 4 Series
KBB.com Review
Kbb.com Expert Rating
The 4 Series coupe and convertible are essentially 2-door versions of the BMW 3 Series. If you want the well-regarded driving dynamics of that sedan in a sleeker package or with a retractable-hardtop roof, the 4 Series is it. As for the 4-door Gran Coupe, it blends fine handling, sharp looks and strong practicality.
Impressive as the 4 Series lineup is, these luxury-performance coupes aren’t the only game in town. You may prefer the tech advances of the Mercedes-Benz C-Class coupe and new Audi A5, or the fresh and fluid lines of the Lexus RC and Infiniti Q60.
