It s always difficult to be objective about what you have and what the others have

... it's the same with cars.
The fact that some of the car you have in America like acura, mustang corvette can't be found in France, might also be one of the reason why I think about these cars.
Driving in france you mainly see french car (peugeot, renault, citroen...) and this is most of the time small cars with diesel engine (because of the price of the fuel).
But I will not complain my car is nice and powerfull..
I was thinking that you can buy foreign cars without too much difficulties in America like BMW, mercedes, porsche, audi... these are good cars indeed (expensive also).
I spend most of my time in Switzerland, and this is a country where you can see very nice car, probably the good cars you were mentionning desal75 : BMW M3, mercedes cls, audi RS6, Porsche turbo, aston martin, maserati, ferrari...
just to go to my office I see everyday few of the one in the above list on the road.
