I mean, seriously. It's the epitome of un-cool. But now I want it?

Yeah, I was looking for E46's on CL, and ran across a Smart. It was $5k, and blue. Non-cabrio. That's it really. But I figured it would be unique... Or something.

Is there an aftermarket? What stops me from mounting a 1400cc super bike engine to it and going like hell? Maybe like a big turbo too? Idk.
