Curiosity got the better of me and I went to look at the car.
It has RUF Wheels, steering wheel, exhaust tips, side mirrors, front lip, turbo tail, dashboard RUF badge a couple of RUF decals and a CR2 decal. No indication of modified suspension or engine.
You are correct in that it was an assembly of RUF parts - under their RUF-FINISHING program (found it buried on their website).
Story gets more interesting - current owner has had it for 6 years and put 2,000 miles on it in that time (odometer indicates 40K miles total)- and it's an ROW spec (WP0ZZZ).
Unfortunately no option sticker visible, but did find a couple of stickers in engine bay with what appears to be Japanese characters.
