I've seen 3 so far.
1993/94: XP5 at the Amsterdam AutoRai
1996/97: 16R or 18R at Motorshow Essen
2003/04: 11R at Copenhagen Motor Show
Only took pictures at Essen, but those are still somewhere in the basement, at my parents
Don't think I will ever be able to match the numbers seen in the other posts......UNLESS there is a big big gathering in the near future, that I can attend
