I don't have actual proof one way or another, but I really seriously doubt it.
Besides, I don't see Toyota offering a special color available on the NA, but not on the TT.....not to mention, the only pearl white mkiv's I've seen were painted.
i know of a pearl white SupraTT that was running around here a couple years ago; i'm pretty sure it was a stock paint job because the engine bay was pearl white too... had a veilside kit on it... was automatic
very sure it was TT
Yes the N/A SE supra was avaible in Pearl White.. I know because i have one. In the sun the color is stunning. I still have my orginial Window sticker. It is a pearl white. I'll have to check i think it might have acuatally said diamond pearl white.
