Wingless haters, go fly a kite.
That said, only certain cars look good without the spoiler. Not to toot my own horn(ok maybe a little) but black is just about the only color I find it really attractive in for various reasons. Since things like the sunshade, mudflaps, lip, bottom of the stock sideskirts, etc are all black, the car looks more balanced as a opposed to another color where those things would be contrasting. The sunshade helps alot...
I'm not really a fan of the pre89 look anyway but without the wing it doesn't really help at all.
But that's just me... Everyone's taste is different.
