So Brad, you think body kits are ok to go on less expensive cars, but on cars in a certain "class" they are not ok? Don't be such an Elitist or make such general statements...
To answer the question, oh wait, the question needs to be clarified a bit. To me, that is like asking if wheels are gay, or if windows are gay. Is there a specific body kit that you are referencing?
I think most body kits out are pretty tacky. The nice ones, like the one on the black Supra above are few and far in between.
