None of these cars are rare at all, maybe closest to being rare would be an automatic 5 speed STI which is available in Japan.
God damn, a mass produced modern day car is nothing rare.
A 9-2x is rare.
a limited trim model from a regular popularly marketed for over a decade with a different badge is not rare. Uncommon, sure. Not stateside, yes.
But not rare at all. You can pop into a Subaru Japanese dealer, lay down several million yen and roll out with a new #204/400 Subaru WRX STI Spec $*$*$ &&& which they release in yearly intervels as a marketing tool.
If you don't believe me, go to Japan and buy one yourself.
