Well looking at the GR Yaris configurator in Japan/Europe you pretty much get everything up from with a choice only in the circuit pack.
So I’m assuming a GR Corolla will be loaded at that 37ish price range and maybe the rumored “rallye” package will be like the circuit pack. From what David (AutomotivePress) has said, it should be more then them just talking a XSE and dropping the engine and AWD in. Just won’t be as extensive as the GR Yaris.
