In North America Toyota already has the GR Corolla, GR Supra, and GR86 but if they wanted to I think they could add more models and sell them easily.
Maybe something like a GR version of the Tacoma and either have it as a performance off-roader or a street truck. Or maybe make a GR version of the Camry since they already make so aggressive looking.
Would anyone else want to see something like this? Or are the three models Toyota has enough?
