I picked "If they are done correctly, then its cool."
I beleive in making the car look good. If there's a pin hole in the body kit, it definatly needs to be filled. I like the cars to look realistic. You have to make sure not to spoil the cars looks.
Other than that, usually I like the look of a stock looking car that appears to be heavily modified... under all the skin. Especially old-school drift cars, like AE86, Sil-80's, 180's, etc. Things like adding a simple lip or spoiler can definatly improve a cars looks compated to a full body-kit.
