Have you guys ever gotten to the Coffee Break on Super License? In that one you have to navigate a maze, in a Honda Beat trying to knock down every cone along the way. What Sportwagon just made was a recreation of that maze. All he needs is a Hot Wheels or Matchbox Honda Beat (which might be a b**** to find since I don't think they made those.)
EDIT: Disregard my last, it turns out that they DID make 'em. But they were exclusive to Japan and have Goofy's face on the girly paintjob.
You know you're playing GT4 too much when you set out to find Hot Wheels and Matchbox cars of the cars you own in the game.
