16: E12 M35i
Dating back to 1972, the E12 is perhaps the most storied BMW line. The car was one of the most luxurious and stylish at a time when BMWs were still evolving. Everything about the E12 was a groundbreaking car, but the M35i was unusual. The car broke the mold when it comes to design (via Motor Authority).

Boasting a 3.5-liter M90 straight-six engine, the E12 M35i was exciting and fun to drive. The styling of this car was reminiscent of a new generation of beamers. With split headlights and a luxurious interior, there was nothing else like it. Genuinely speaking, the M35i is a blast to drive, even today.
