I would venture to say have a "sunday cup" that races various models of nissans. Most, if not all should be street driven. It would be like autocross but on an actual public / private race track. (vs a makeshift one like in autoX) Kinda like the one in PS2's GT3. Only need 1 or 2 events per metro city. Throw in product support for parts at a good price and a little prize $$ but major bragging rights would still make people want to enter. The only downside is accidents on the track and what not, but waivers would take care of that. Something like the sunday cup meets JGTC time attack.
