I've always liked the Infiniti G35/G37's, namely the coupes (because of course i have a soft spot for Nissan Skylines), but the sedans don't bother me; they're just not as good looking.
I've always loved the '90's-era Thunderbirds. they were probably the closest thing there was to a true musclecar back then (being that they were midsize RWD coupes)
When I was a kid, my best friend's brother bought a brand new '94 or '95 Ford Probe GT. We thought that thing was the $h! back then, and even today I can't bring myself to dislike them, even now knowing that they were FWD and meant to kill off the Mustang.
Classic Japanese sports cars like the '69-'72 "hakosuka" GTR's, Datsun 240/260Z's, Mazda RX-3's, first-gen Celica GT's, including the Mk I Supra, oh, and of course the 2000GT.
E30 M3's
BMW 850CSi
Subaru SVX's had a quirky appeal. They don't look like much in the way of a true sports car, then you find out they have 230hp and AWD (remember, this was 1995 or so).
Subaru BRAT (namely one I saw online once with an STi motor swap)
Subaru WRX STi's and Mitsubishi Evos. Namely GD-3's and VIII's, respectively.
Nissan 240SX (S14A's preferably).
Ferrari 308 GTS, 288 GTO
Any generation RX7
Latter-day Pontiac Fiero. Ditch the Iron Puke, swap in a GNX motor.
