I'm hoping the Competition Series will be available with the manual A/C referenced in the owners manual. I'm still trying to figure out the logic of two sets of A/C controls. I've seen nothing to suggest different interior content packages for the regular cars beyond material selections. Seems unlikely there is an "econo" interior package with manual A/C for the regular cars, but I can't be sure.
The manual had no disclaimers or references to a supplement regarding a "Competition Series." I think this means it's not a serial number-only track special, but a street legal package. Also, despite what the Web is speculating, I would bet these cars are included in, not in addition to, the planned production run.
