I loved the M2 at its introduction because it was fun and furious, a small fast BMW that reignited the M flame. Little did I know it would get better with age while infecting the M4 CS with its joyful, attacking style. All while being as docile as you could hope when you don't want fireworks (and there's an M2 CS in the works, which will most likely be unhinged).

It's the only one of its (mostly) German rivals that is rear-wheel drive, six-cylinders and two doors. The A45 is fast and exuberant, the RS3 offbeat with its five-cylinder engine, and the Golf R as dull as dishwater if eminently capable. The M2 is more fun than any of them, if not as practical. But for $100,000, it's unlikely practicality is your prime directive.

M2, RS3 or A45 (see what I did there?) - what's your poison? Tell us in the comments below.
