Agreed Sars, I love them all. Personally, having been chauffeured in an F40 in my early twenties by a friend of my Dad's at 260km/h it will always have a special place in my heart. Henry Catchpole is right - when the turbos cut in the ferocity with which it catapults you up the road is incredible. I have never been in a car like that since!
The Carrera GT sounds incredible too.
I think though the standout car from that lot has to be the Mclaren F1. It was revolutionary in so many ways. It will be worth £20m in years to come. Oh and it's powered by a BMW M V12 too.
Been a passenger twice in the F1 whilst testing at MIRA early nineties, once with chief mechanic driving and once with Gordon Murray. Incredible acceleration and even more incredible sound!! This was the silver prototype XP3. I had to sign a disclaimer first to say it would be my fault if I was killed.
