The one thing that I had to learn the hard way afterward that no one talks about is that this car really isn't a "fanboy" car whatsoever. What this mean is that no matter how good it is in the reviews, no one's really talking about it nor does anyone care. If you can find a local group, consider yourself very lucky.
While the BRZ/FRS has weekly/monthly meets, spontaneous last minute meets, and their huge annual Aug 6 (8/6) meetups, it's like pulling teeth just to get anything more than a 5 car FiST meet up in my area, and that's if you give 3 week notice to see if people maybe feel like coming out. No one's excited about it. Seeing one in the wild is rarer than spotting a Ferrari on the road. Something about that seems wrong, lol.
Just a complete different culture. I met a few owners at a local autocross. Seems like most FiST owners are just happy doing their own thing and enjoying the car, but no car club necessary. (Oh, and in that same autocross, the 20+ BRZ/FRS that showed up decided to all line up in the parking lot and take a photo, just because.)
