Uh, so this representative sample is taken from ONE car, for ONE year? I think the long-term tests are more for the purpose of seeing how people like the car after driving it for a while, not for reliability study. The sample of one car is basically meaningless. BMW's are just reliable enough that reliability is not an issue for buyers. Lexus is so reliable that is becomes a positive issue for buyers. The reverse is true for companies like VW, Volvo, or Saab.
