Oh boy oh boy oh boy, here's the vrooomtabolous and akiratastic ARTA Super GT 300, the nemesis of Mach 5, our favorite car this side of the Batmobile. In fact, if the Joker liked race cars instead of trucks and school buses, I'm sure he'll grab this one and beat the crap out of Mr. Pointy Ears. All that red and shapes remind me of Kaneda's bike:
This bad boy belongs to a real Super GT team from Japan called Autobacs Racing Team Aguri or ARTA, and sports the same team colors.
