I'm not typically a fan of re-badging cars to make them seem like they're something they're not. For example, I'm not going to put an M3 badge on the trunk lid of my 318is... but I do find that some M parts can look attractive and offer some good function too.
So far I have an M tech II steering wheel and an M shift knob. The steering wheel feels great compared to the stock airbag wheel and the shift knob shortens the throw and feels good over the stock knob. And of course they look awesome! I have thought of another small cosmetic detail I had thought of doing and I figured I'd bounce it off you guys to see if it would be neat or lame.
The idea.. E30 M3s have the M3 badge on their front drivers grille... What if one was to take an M badge, a "4" from a 740il badge, and a "2" from a 325, 525, whatever... and put them together to make an "M42" badge, glue them to a small black plate and attach it to the grille ala M3. Yay? Nay? Opinions? I suppose the trick would be to finding numbers and an M badge of the same height and proportions, but it might be possible.
