I would say if I had focus rs type money to burn, I think I would have a Monaro or a vxr8, and get it supercharged. Always wanted one ever since they came out, and I am a huge fan of Australian v8 touring cars. I was looking through auto trader a month back, and there was a 5.7 Monaro Vxr with a TWR supercharger kit on, and the suspension and brakes done, for £12k. Admittedly the fuel bill would be horrendous, but the smile it'd give you would be enormous.
