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.
