Here's the silly thing about it all, I've always explained why I don't like the car. The words are coming from me and only me. People can take my words however they like, to be honest. I'm not running about just spewing things with no substance to back them up. I have the same concerns and reservations that many others do, as well.
It's a great starting platform, but it's not the finished product. It's like that one good in school that teachers are disappointed in because he shows tons of potential, but doesn't use it - that's my disappointment in the GT86s. If Subaru releases an STi version of this car, that one will be bonkers and outsell the base car - take my word for it. Much like Jaguar thought their V6 Supercharged variants of the F-Type would outsell the V8S and R models by a ratio of 3:1 - they were dead wrong. More people are dropping the extra $40K for the V8 models, instead. Sports car fans will flock to this car maniacally, they will considerably eat into sales of pre-owned BMW 135s and 335s, 370Zs, G37s, Mustangs, Camaros, etc. etc.
I'm relatively certain the reason why Subaru isn't releasing an STi version is due to some contractual issues, they're probably not allowed to one-up Toyota.
