Honestly I don't see anything wrong with doing a conversion. We all do appreciate giving our rides a sporty image right? It could be abudget restrain from getting the real thing but hey, I'm happy with the ride with just the looks.... To each his own tio boh?
As for the feeling that a genuine owner has of feeling cheated, I guess it only applies when you use your car to show off your status? I don't mean it in a insulting way don't get me wrong. But if 1 day I am able to purchase a nice car like a M5, M6 or SL55 I wouldn't give 2 hoots about the car next to me even if its a very very nicely done up "fake". Yea so this is what I personally think of "fakes" on the road lor...
