Mansell, best F1 racer I've seen. Always gave it 100%, even in slower cars.Not the greatest driver, but for my money he was the most entertaining to watch, British too, hence my fav.
Because I only started watching f1 in 2007, my favourite driver as an all-round person is Massa. Alonso is faster, but he's also a massive prick. I could imagine having a conversation with Massa, whereas Alonso would be too 'high and mighty' to converse with a member of the public.
I'll bet if you had caught him in the act,he would have said "No hard feelings old chap,let's go for a pint".
