The Prize Car thread up top has the full lists for both the NTSC and PAL versions. Anyway, the ARTA NSX is a prize car for the Amateur All Japan GT championship and the SS11 Endurance.
I would like to have a collection of all the race cars on GT3, but that will take some time. That includes all the LM's and the NSX's, too!! That would make a nice array for a picture, wallpaper, or something.... :burnout:
