the trickiest car to drive ever

[Ford Capri 2.8i]

Im just like to know which car is the trickiest for driving ever in the history of the car for other members...i mean the car that requires the most skillful abilities to drive it into the limit or in wet

for me the decision is not very clear....but there you go 3 cars
- the 1978 porsche 911 turbo (4 speed gearbox) (back engine, no setting for understeering, an engine with a big punch, no progressivity)
- the renault alpine gt turbo(a car with identhical philosophy to the porsche 911, with a brutal garret turbo in it....a very high limit due to the tyres and suspension, but brutal on limits)
- the renault 5 turbo tour de corse.....a mid-engined car, but with a very short wheel base....and a big turbo in the car to get about 285bhp for a 1400 engine
