I can't yet imagine wanting more power than my stock UK MY2000, though I expect I will one day.

I still scare myself occasionally when I accidentally hook up a really good get-away from the lights and find myself pinned to the seat and fumbling for 2nd gear...

What really worries me though is that just about any other affordable performance car that I buy in the future is going to feel slow. If I don't pluck up the courage to buy a TVR Tuscan then my second choice is a Boxter and that it definitely going to feel slow compared to the Scooby.
