At the risk of infuriating people in the 'I've got more YRF2's than you competition..."
These are just the ones I was able to find quickly. 2 MIB sealed YRF2 Specials, 1 MIB sealed YRF2 standard, I Mint built YRF2 standard, I Velo-Spec YRF2 standard race car, I YRF2 Special race car. There are two other built cars somewhere, plus a big plastic case full of new spares...
And no...don't ask, not for sale!
