I know I'll offend alot of people here, but I don't like pretty much any aftermarket, non OEM exterior accessory, and let me explain why. For my taste, I like the way a car looks or don't like the way it looks from the factory. Gaudy accessories add weight, hinder aerodynamics, and really can't match PERFECTLY with the car's color (unless you paint the whole thing). I say show me a sleeper. I have much more respect for someone in a car that looks completely stock, then blows you out of the water. That five grand you have in gargantuan spoilers, ground effects, colored wiper arms, illuminated washer jets, indiglow instruments, and whatever else can be used to make the engine into a brilliant performer, and no one will know but you. Not to mention, I really don't care to add to the attraction to theives by making my car scream "hey, look at me!!"
Just my $.02.
