I've had two different Porsches, a Cayman S and a Macan. Neither gave me a day of trouble. You just have to do all the maintenance, which is obviously expensive.
This seems like a totally crazy statement. The only common thing that a current and 50-year-old 911 share is that there are six holes in the engine block.
I wonder if Porsche is allowed to exist in point where they are not fully cost optimised so there is more spend on those slight things that keep reliability. Most other large manufacturer cars seem to be cost optimised while least amount of that is carried over to customers...
porsche is part of volkswagen, so it's not that surprising that they're decently reliable. i probably see 10 porsches for every ferrari, lamborghini, etc that i see, and i think a large part of that is reliability - even absurdly rich people don't want to deal with an unreliable car when there is a more reliable alternative.
