Why are European cars so bad and break easily?

German, British, and Italian cars tend to have the worst reliability and fuel economy. This is especially proven by the consumer reports of the past decade.

American cars have good reliability and fuel economy so why do people buy European cars over American? American cars should cost 5 times as much as the European cars because American cars are 5 times better than the European cars. Instead, European cars are the most expensive for no reason.

European cars are unreliable and waste too much gas without going too many miles. So for 200 million dollars or more, what do European cars have to offer? Just badges that say Mercedes Benz, Lamborghini, or Bentley?

If people didn't fall for the lie of German engineering, more people would have been buying American cars and the American GDP and economy would have been much larger than they are now. America's GDP would be much larger than that of the European Union.

More people should start buying Ford, Chevy, Buick, and Lincoln.

Added (1). I'm writing a research paper on economics for my college. Thank you for answering.

Added (2). I was obviously being sarcastic and I exaggerated the price of European cars, but you guys get the point. Most European cars cost at least 60 thousand dollars and for no good reason.

1988 Four Winns for sale for $750, but has milky oil dipstick. Should I go for it? Thoughts?

Right down the street from me, there's a 1988 Four Winns for sale for $750 OBO. ITS VERY CLEAN. The man says it starts and runs and the IO tilt prop works. He made a video to back all of that information up. However, he forewarned me of a milky oil dipstick, he does not know much about engines. I know it has to be either a blown or cracked head gasket or a cracked block. But I read a lot of articles that say it's more than likely the head gasket.

But, if it is a block, is it true that I can repair it myself with JB Weld?

The engine is a Ford 351.

Paint problems on Mercury Grand Marquis?

The paint is flaking off my Grand Marquis. I first noticed when using a high pressure hose at a car wash. Started looking the car over and found several places where the paint seems to be just falling off. Is this common with Ford/Mercury products?

What is causing my car's AC to make a hissing noise?

I have a 2006 Ford Crown Victoria Police Interceptor whose HVAC system makes a hissing noise when I turn it off. When I put it on normal AC, Vent, or any other setting; it goes away. But if I put it on Max AC or turn it Off, it makes a hissing noise. It sounds as if it is running, but it is not when I have it switched off. It blows cold and hot when I want it to, I just want to know what the noise is. Also: it only happens when the car is running. If I turn the key to the #2 position before the ignition, it doesn't make the noise unless the engine is running. Any idea as to what may be causing this?
