thanks for the repies guys.
I know some think its silly to consider economy with performance car, i of course if you out the hammer down you will drink heaps, but i need a car as a daily, fun to drive but with be easy on the wallet if i drive easy!
Hense the question.
One option i have concidered it to do an LPG conversion and then you can have the power and economy. LPG loves high compression and so you vould really boosts it. Just need a decent size boot to fit the tank.
