I'm with Poggy, ok Fiat do and have done some excellent cars, particularly the 500 I guess, but the greatest cars of all time? Hmm.
I've voted and my list is very similar to Jonnys but included the Model-T ford, WW2 Jeep, Jaguar E-type instead of the Lotus and the Lancia.
I use 4Car a lot it is one of the best and most detailed review sites on the net - but as with all these things I suppose it's impossible to please everybody when you draw up a list like this! What a joke though I mean the Merc A-class? That's just an ugly punto class car that's three times the price!!!
