Does anyone have any experience with this body kit? I've seen them advertised as high as $19,500 and as low as $5,500. I get the sense that he started high and couldn't sell them, kept dropping the price. The photos in the ads don't give me a very good impression of the quality - but that could just be the photos. I'm planning to start an Aventador replica one of these days, just doing early research. Thanks!
