Many of the cars have special parts available at Tunerz Paradize, but not all of them. The options available for each car also vary. There are body parts galore for some of the cars, and for a few there are only headlights and taillights. On the up side, the cool but extra costly rims will go on any car.
Check out these screenshots of two Sakura GT20s, one that is customized with option set a, and one with option set b. Plus custom rims. Yes, the more expensive option set does affect the sale price.
