Chuk,
There's lots of stuff that never makes out here (or out there!!) that remains onshore in Japan.....have a at the Hobbylink Japan website at:
http://www.hlj.com/
Fujimi makes one - or makes several - they all appear to be on back order with HLJ, and also appear to be racing versions, but other than the rims, tires and possibly the interiors, they really don't look much different from the ones I've seen driving on the road.
Can't tell you what to do to order one - I've never ordered from HLJ.
Good luck!!
