Wow, this thread went down the drain.
Anyway, I still contend that for the average person, a German car is more unreliable regardless of maintenance. We've had 4 German cars and each one has had its share of problems; whether it being small electrical nuances to big problems (my mother's E320 lost all power on the freeway out of nowhere). It's not like we skip any services or warning signs, we take the cars in for their regular services.
Yes, any car can last forever as long as you maintain it properly (no duh), but let's not pretend that all cars are on equal footing in terms of real world reliability. All car parts eventually need to be replaced, but reliability in the eyes of most consumers seems to be how long between replacement/service intervals they can drive without problems.
Even if the consumer definition is how long they can abuse their cars before they break down, isn't that a valid point in discussing reliablity? The Land Cruiser built its reputation on how much punishment it can take. A person is deemed as reliable as long as they are consistent in what you ask them for while we ignore what they go through to meet our expectations. Electronics are seen as reliable as long as they keep working without maintenance. I doubt a DLP that has to be serviced 2 times a year is seen as reliable compared to an LCD without any servicing even though both are still working. Yes, you can service the DLP to keep it working, but that's where the perception of reliability comes in. When it comes down to it, car reliability is gauged on how much abuse it can take.
