first, let me say that is one hell of a garage with 3 V35's!!
and yes its probably a case that most that can afford a V35 are more mature and as such won't want what you are looking for form their V35
i am 25 and i would probably consider myself young to own a V35, but 21 is even younger!
cancertainly do whatever you like to your car and we won't care in the end and will still offer our help on SAU when we can, but if you are asking for advice or opinions in this thread - then my opinion, like graeme, is that these cars are more luxurious than racer and i prefer them left more stock-looking
but at the end of the day, people modify all sorts of cars from skylines to mercedes' to bmws, hell even ferrari's!
