Y'all keep saying "again". From the looks of it it's not the same thing. D1usa wasn't D1. It was some dudes trying to make money using the D1 name and bringing over like 4 D1 drivers. I'm probably wrong, but hopefully not...
Anyway, it probably is pretty expensive to drive. Aren't FD events pretty pricey? I mean $350 ain't nothing when you're driving a semi to the track.
