Haven't taken time with all the fabulous 4WD's yet, so much to look forward to in GT2 yet!
As for the FC's, they're all great because they're so easy to handle, and get bonus points for being probably the best affordable sports cars of the time
except the '90 cab, too heavy, 50/100
'90 RX-7 GT-X gets bonus points for being a seriously cheap used car, 70/100 modest ultimate potential
Infini III gets points for being maybe the best starter car and it's so easy to handle, but still only modest ultimate potential, 85/100
The '91 type R (still an FC right?) has the best ultimate potential but I'll rate it under the Infini because it's not a starter car and is pretty much otherwise just as good after tuning (though it starts off with more power), 80/100 -- oops, scratch that, '91 was the year the FD was introduced, so this one's not in the FC category...
The FC was a great model for its time, for sure!
Curious now if anybody rates the Angel T01 decently, I found it too challenging for my taste, but maybe it's my inability to set it up properly...
