That was all true during the film era (although the Leica film cameras never were as reliable as their marketing hype told they were, but this is another story).
Now at the digital age, a Nikon D700 with a good Nikkor lens would be a way better choice for the modest photographer ready to drop $1000 in a second hand kit which will take picture after picture without any problem and may virtually last forever without any maintenance or repair. The D700 was marketed long ago enough now so we all can know how highly reliable it is.
Someone I know just sent his M8 to Wetzlar because that camera (which he had bought from new and always used as a careful amateur) suddenly ceased to work. The camera came back and the invoice for the repair was 1,075 euros. And if you consider what happened to almost all the M9 units... well.
I don't belong to any "anti-Leica brigade" but we all have to acknowledge that, today, the digital Leica Ms are everything but reliable cameras which will be used for taking pictures for a lifetime without forcing their owners to spend top dollars on them for repair on quite a regular basis. So, buying a new digital Leica today means, nolens volens, continuously spending money on it even long after the purchase day. Another kind of debt...
