I'll believe it when I see it. I have trouble swallowing the idea that anyone could sell a US$16,000 RWD sports coupe. And there have been numerous rumors that Toyota would be getting back into the enthusiast car market, but they've always turned out to be false. I can't remember for how many years now the rumor-mill has been predicting a new Supra.
That said, if Toyota builds this, and sells it for under $20k, and it's actually a good sports coupe, I would be very, very tempted to get one.
