The following is a mere observation/personal opinion,it is not meant to claim that one country is better than the other automotive-wise.
England and Italy are the top two for sure,but trying to determine which is best will end up in a blood bath,personally I tend to lean towards the UK,but by a very very narrow margin.it's true most italian cars have what we call "passion" and "soul" but i find most italians to be unatainable for the common people on the street,but england have always been a producer of cheap thrillers with it's TVR's,Caterhams,Nobles,You know the kind of car you buy to drive and not to be seen in,abd I am afraid to say most italian marques have become "too cool"(hence most ending up in the uncool section of top gears cool wall)..even the afforadable one's(alfa) are suffering from reliability issues so it will take brave man to opt for one,FIAT however remains the exception.so my observation is italy is exceptional at making cars that make great posters on a teenage boy's wall,while england is great at making cars that teenager get's to drive and own.
Anyway I think the coolest two cars of today are the Rolls Phantom Drophead and the Alfa 8c.and that just sums up where my loyalties lie.
