Statistically speaking, every car is within 1 percent + or - from any other car... anywhere.
There is just a general feeling that foreign automobiles are better... The real thing is that Japanese people buy Japanese cars, Germans by German cars... Italians and so forth... However, in the States, we like to buy whatever is the cheapest... Just our capitalist nature.
I don't really think any car is better than any other... I've had Chevys and Fords that have gone great distances, but I guess we all just like what we like.
