Japanese cars are superior to American cars

I had a high school friend who went on to become an engineer at General Motors. One of his first projects for them was tearing down an Infiniti and a Lexus when those cars first came on the market. He said that at the time, GM cars typically had between 300 and 400 production defects of varying severity. When they took apart the Infiniti, they found 2 production defects; when they took apart the Lexus, they found 0.
