But of course, the only proper colour for a Supra...
Quicksilver is a different colour btw, gunmetal is 6NO on the chassis plate, quicksilver is 1B9 I think. If you want to find out what model you have, have a look on the chassis plate at the model code. It will be E-JZA80-A followed by 4 letters. The first of these is J for an aerotop, L for normal. The 2nd is F for manual, P for auto. The 3rd is the one you want, Q for RZ, S for SZR, V for SZ or RZS and Z for GZ. The 4th letter is F for non-turbo, Z for turbo.
So mine is a E-JZA80-ALFQZ, the one to have of course...
