get something RWD imho.
depending on budget...
ae86s are still way overpriced, though the market for them looks to be dying off a bit.
you can pick up carinas and coronas for cheap, and carinas in particular can look freakin awesome! and if you are willing to hunt you can find them with IRS as well.
havent had much time behind the wheel of an AW11, but they are highly spoken of, and i always liked SW20s.
if you are looking to spend more... RX7? S2000?
oh and what revhead said - drive a bunch of stuff and find something you really like.
