you should use your car as your pallet to express yourself. if thats what you like, do it.
ditto. a car should reflect the way a person feels about it.
that said, people should know exactly what they want by doing research so they make good decisions the first time around. throwing things on a car just because they are available is what we like to call 'rice'. also, many people want peole to like their cars (for most peole, what other people like is just about as important as what that person like himself/herself).
not pointing fingers at all or even saying thats true in this case..that's just my viewpoint as a whole on this subject
