I don't play PCL but I was into that stuff before PCL was around. Basically, you just own the picture. You purchase it and now you can put the picture of the car in your sig. After you buy mods for it, you edit them into your picture however you like. Bought an exhaust? Open up MSPaint, Photoshop, whatever and draw a skinny tipped exhaust or a fart can, doesn't matter. You're also supposed to keep up with stats & specs yourself.
