In case you were wondering, BMW never built a pick-up E46 M3, but for some reason more than a few people decided that it would be a good idea.
Enough people, in fact, for BMW to use it as the basis of an April Fools Day prank a few years ago.
We even know of at least one V8 M3 bakkie conversion right here in SA.
The E46 M3 was equipped with a naturally-aspirated straight-six engine, good for 252kW and 365Nm of torque. It was already an oversteer monster to begin with, so just imagine what happens when you remove most of the weight from the rear wheels.
