given your spec i really would consider a hot hatch/gti/ gt tourer
Mk 2 Golf brilliant classic car
Lupo GTI.............absolute fun and semi practical
polo gti 150 bhp version
renualt twingo girdino......not driven one but look fab
Mitsubhsi Colt czt
MX5 as above but at 15 stone and 6ft did not really fit in that well , not mega quick but fun.
Z3/$ bit underpowered but nice
TT looks fab seems to have a few problems
Nissan or the Honda are both great drivers cars , the Honda is designed to pootle if you want or rev it hard and is a monster.
The hot hactch you can get in your price bracket,and have a nice bike holiday
