Last month, Toyota revealed a more extreme, track-focused version of its hilariously fun GR Corolla hot hatch, with the new model being named the GRMN Corolla. For not much more money, you can get yourself a Final Edition Toyota GR Supra for $70,645. Can any Toyota Corolla be worth that much? The GRMN Corolla makes almost as much power as the Supra, despite having an engine half its size. So, it isn't just a GR Corolla with some cute extra badges on it.
