Id say his best car is the one that hes able to excel at, whereas the likes of clarkson utterly fail... Hence probably some sort of TVR.

Ascari simply becuase Clarkson and probably the majority of us would not be able to drive something that was clearly not made to drive on pnulic roads.

The challenge with the ferraris and lambos is getting the seconds out of something that is allready driveable.
