I don't know if I'd say they have an even, predictable quality, but on an actuarial basis, Detroit certainly makes for easier claim severity modeling than anything out of Ingolstadt, Muenchen, Stuttgart, or Wolfsburg.
That said, I don't really understand how quality maps to cars beyond what my comprehension of Japanese has allowed me to read about how Toyota's industrial engineering contrasts against Ford's. My first may have been a 1971 Opel GT that I salvaged by bringing home in parts on a bicycle-drawn trailer as a teenager, but I only ever wrenched on it. I never drove it.
