2018 BMW M3 Sedan 4D Depreciation
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
Whether you’re a longtime enthusiast seeking the highest-powered BMW 3 Series sedan or simply want immediate access to an automotive icon, the M3 will grant your wish. Rolling up in an M3 shows you have taste, passion and a love of performance.
The BMW M3 is hardly the only game in town. The Mercedes-AMG C 63, Cadillac ATS-V and Alfa Romeo Giulia Quadrifoglio are all more powerful and have smoother automatic transmissions should you forgo the manual. The forthcoming Audi RS 5 has its own twist with standard all-wheel drive and a sleek yet practical sportback design.
