If you compare a few years of the very reliably representative Annual Consumer Reports Car issue which color codes components of the car like trans, engine, ride, structural integrity, A/C etc and then weights it out for a composite score, you'll see that in general, across the board, cars are much more reliable than they were in the past, especially those coming out of Detroit. However, the most bullet-proof vehicles have always and continue to be Japanese although ironically most are now assembled here, but to Japan's specs, QC supervision and often with imported parts. American cars have improved, I know people who swear by them. They've come a long way from the old admonition that you don't buy a car from Detroit that's been manufactured on a Monday or Friday (drunk, hungover assemblers etc) , but Japanese cars, like the Lexus are among the best made cars in the world.
