Why do we avoid certain cars? How about by country of origin?

JD Power is a very large and influential service that monitors almost everything, then puts the information down in a relatively easy-to-read manner. Many people out there use JD Power's information to make an informed decision when it comes to purchasing a car. So, it was with interest that I read what responders to a survey by JD Power had to say when it came to the top five things wrong with cars by country of origin. Not surprisingly, American cars were blasted for reliability and fuel economy and technology. I was a bit surprised to see that European vehicles, (brands like BMW, Mercedes, VW, Porsche, Jaguar... Ferrari) scored better on fuel economy. Perhaps they do in Europe, where diesel vehicles are widespread, but not necessarily here in the States, which is where this survey was conducted. Or maybe it's just that shoppers for European vehicles in the States are not as concerned with fuel economy? What do you think?
