Here's hoping dealers aren't fighting each other for them, but I bet that will happen+1, I talked to the owner of the Toyota dealership last month and he said there are no GR Corollas in the US, other than the ones used for promotion. That he is scheduled to receive some (already sold...) mid to late fall this year. And he added that Toyota sent them a letter telling them to limit the pre-orders early this year... apparently, they have more orders than the amount of cars they can produce at this time. I think the GR's are built in just one specific factory in Japan. He said to check the Road and Track article online... I just found it, it's from April 2022.
This is the same thing that happened with the C8 Corvette when I was working at the Chevy dealership. August 2020 they were told to stop ordering C8's, because the quota for 2020 and most 2021 was already allocated. Every C8 that arrived at our dealership was sold almost a year in advance, and we were only receiving 1-2 a month.
