if want pure , can take a bit further than a Lotus,
experienced our local TVR gang, 4000-5000cc , 1060kg fibre body convertible, 3.7s for the 5000cc. it take 0 to 240kmh with no hesitation. Only with the LP640 level of engine power can fool with it. These are pure mean 'machine', the engine could heat up like an oven anytime. Only 8 in our whole city. I was not even dare enough be 'qualified' to sit in one, not to say to drive it.
CSL?
No, I shall stick with a nicely balanced , more gargets and a safe M3 V8.
