If you want a pocket rocket then a 4.4 sport (1600 Sigma) at 795 kilos is the way to go.
If touring is your thing, a V8 will probably be your weapon of choice.
If you are a millionaire, an Aero may float your boat.
All except the Aero lend themselves to aftermarket mods to improve handling and power.
If you end up with a trad, put a set of Avon vintage racing tyres on and the handling will radically improve straight away.
