Picture caption: "Many of you know I’m not a Supra fan. That’s because they suck compared to a GTR. But you gotta give props to a Supra from Top Secret with a twin turbo V12 from the Toyota Century. Smokey is the MAN!! It makes “only” 600hp, but the car is still new and untested. I think Top Secret is still wasting their time (man, did I write that?) on Supras because there aren’t too many sports cars in Japan at the moment."
