1) Prelude 2) Integra 3) Miata
The prelude, IMHO, is dead sexy. I've seen some really beautiful tuned Preludes that are from 97-01 and not only do they look incredible but they're faster than my v6 accord. The Integras are nice, but acura parts are more expensive to replace than Honda Parts. Seeing as how you want to spend more money on tuning, you might want to take this into consideration. The miata..ehh.. too small for me. This answer is biased (since I have a honda), but take it as it is.
