Lots of cars have been pitched as BMW M3 killers, from Mustangs to Audis to Pontiacs (probably). They have been rarely successful, but always interesting. Which are some that everyone has forgotten?

The above car is a Mercedes 190E 2.5-16 Evolution II, the final iteration of Mercedes' original M3 fighter back when the two dueled it out on DTM tracks across Germany. I like to think of this car and Cosworth 190Es that immediately preceded it as the original M3 killers.

What other M3 fighters have been lost to history?
