Just found this picture on flickr of a Graco Quattro Tour that a dad pimped out for his son Max. Sure, the ground fx and the decals are the most immediately obvious mods, but check out the silver-painted wheels. And he outfitted the canopy with an mp3 player and speakers. Given the size of the Quattro Tour's console, I'm surprised he didn't install a DVD player, too.
