answer:Some car companies have cornered the market due to their reputation for excellent products. And other companies have sabotaged themselves with a reputation for products that aren’t as good at the other companies. I don’t know if this is true or not, but I’ve been told by multiple car enthusiasts that one of the differences between a Japanese company and an American company is that the Japanese take precision and quality more seriously. Let’s say out of 100 random manifolds manufactured, there are 2 or 3 minor imperfections. One company might say “this is unacceptable, scrap those”, while another company might say “it’s still good, it won’t matter.” This is an example that was told to me that explained some of the differences between some foreign automakers and domestic automakers.
