Wheels make a car, you can have a POS saxo stick some nice rims on it and it does not look too bad. You take the same car slightly pimped up and stick crap wheels on it the whole car looks like garbage.
But agreed some people go over board, a set of 20's on a clio is never a good look
I remember seeing a Renault 5 with 'Hub Cap Spinners'

OMG what a mess, young girl driving it too, bright pink with pink fluffy steering wheel cover.......Wheres the barf bag
