I’ve always had good experiences, even in the dark years US cars were not the absolute toilets most make them out to be, as evidenced by the Mustang II. Many people forget that ALL cars were not as good in the 80s as they are now. How many 1980s vintage Japanes cars do you see on the road?
I have found that lots of folks, once they choose the dark side and jump over to supporting foriegn brands, they embark on a quest to justify thier decision. One way they attempt to do that is to make absurd over-statements about problems with US cars. As if in some fantasy world they have experienced driving around weaving through a chicane of broken down American cars, LOL.
All cars can break, they are made up of thousands of man-made moving parts. Some models are better than others. Car complaint forums are chock full of people with unhappy experiences with Japanese and Korean cars. Toyota, Honda and Kia mechanics are not wanting for work, they stay plenty busy.
