hey alan..
i was and still am in a similiar situation since about a year ago, and i was considering a lotus elise(i know its not in the above list) for a daily drive and maybe some track days...aparently they handle rather well and have a good power to weight ratio...and in my opinion they look good, different and are relatively rare..
the only downside that i can think are the size which may cause practicality issues, the lack of electronics like power windows(which i dont overly mind having less buttons around) and a hard suspension(again i dont mind that much)...
but it is over your budget, 99-00 models range from 40-55k..
and of course it would take away some of the home-sickness that u may still experience from time to time
just thought i would add something different to the list..
