I somehow managed to order TWO extra sets of decals. I need to keep better track of my orders! Anyway, I have one set each: Shunko Decals Toyota 88C-V Minolta for the Tamiya kit $12 Shunko Decals Mercedes C9 for the Tamiya kit $16
$1 shipping in the US.
Looks like Rob has the Mercedes kit for sale in his thread....
EDIT: I also still have a Revell Shell Reynard available for $10 plus shipping.
