btw, this car still available !! but as diligent readers may have seen, i bought the cs last year, and going for a regular c now. but if anybody is interested in this 'neither-fish-nor-fowl' example, it has been re-listed by original owner - ie it never sold.
the other thread asking whether or not a challenge car can be made street legal, reminded me of this quixotic quest i was on a couple years back. i think this car ended up in japan.
