For the most part the Voodoo retains its GTA IV form in GTA V. However, it is no longer a clean vehicle, and now is in a rusted and scratched condition. On the plus side, its performance seems to have improved slightly over the GTA IV rendition. Oddly enough, the clean version is no longer available, only the rusty version which cannot be "cleaned" through modification or car washes.

Geht wohl leider nicht..
