I heard it is possible to convert a 318 to an m3. Of course the most major mod would be the engine. Is there a websight that has more info on this process?

I don't know the website to do this, but the cost of actually doing it would probably cost more then buying an M3 itself. I know this for a fact, well for Australia anyway.

Unless you just want the site for an interesting read, I wouldn't consider this option.

Besides you get all the M3 goodies when u purchase an M3.

what "goodies" do you mean?
