I should have added that I think 04R is also gone. In 1995 it had a heavy crash and the Gulf team had to replace the car with 08R to finish out the season. The poster included with Driving Ambition claims that 04R stood in for 14R at the last race of the Japan GT series in 1996 at the Mine Circuit. I highly doubt that information is accurate and instead believe that it was most likely #08R that fulfilled the role, later becoming the West-liveried "Adrenaline Program" car.
#02R participated in a couple of events in the British GT Series - I think in 1998 maybe. I can confirm when I get back home. That's the last time it was seen that I recall.
08R is in Bahrain (oops) - I'll add the current owner's name later on.
