Nick,

The 4C is anything but underpowered. I can guarantee it could scare the bejesus out of you in the speed department due to the lively chassis smiley It is a very light car and has a power to weight ratio of 259 bhp per tonne. A 991.2 Carrera S has 287.5 bhp per tonne by way of comparison.

The raw experience is down to unassisted steering, the suspension geometry, the low to the ground driving position and the carbon tub and lack of sound proofing which amplifies the noise and lets you hear every stone pinging around the wheel wells and under the body just like you do in a 430 Scuderia etc.

From your posts and car preferences I cannot see it being a car you would enjoy driving.
