With manual and automatic transmissions, rear- and all-wheel drive, and an upcoming first-ever wagon version, the M3/M4 lineup is more diverse than ever. Even though convertibles have largely fallen out of favor in the latest couple of decades, BMW still believes there is a market big enough to justify full-fat M versions of certain droptops in its vast lineup.
