I don't know what's so custom about the tailgate. (other than the Cayenne 'turbo' badge... which is kind of cool I guess... even though it's a ripoff of Porsche) but yeah... the chicken wire grille is absolutely disgusting. Other than that, the rest of the car looks cool. But I'm not sure I could ever buy a car from someone who actually thought that grille looked good. If they're THAT retarded then...
As for the price, unless I'm blind, it doesn't list the mileage. So there's no real way to know if that's a good price or not. Personally, if you're in the market for a CX-7... try to find a cleaner example (or just go new since most dealerships can't even give cars away these days) Turbo anything's aren't something you want to be taking chances with on the used market.
