The Xbox game i believe you are referring to is Wreckless: The Yakuza Mission, which features a DeLorean, or very close look alike... The game is out for PS2 and Xbox, i am not positive if it is out for GameCube, The DeLorean also has an apperance in Grand Theft Auto: Vice City but it is named the DeLuxo and has corvette taill lights with a high spoiler [Non-text portions of this message have been removed]
