It's common knowledge, and I'm sure you were well aware of it, that until recent years the Germans were less than reliable yet you went for it. Nothing wrong with it IMO, more so that you know a thing or two about cars and work on them yourself.
Should they be reliable? Sure, but we all know this is not the case.
I'm of the principle that one should drive the car he likes and enjoys even though it comes to a price. Plus you keep them short term anyway so even less concern.
Speaking of belts, I replaced it proactively on the Outlander, including the pullies, at around 160K / 8 years when I did the timing belt. I try to avoid waiting until something breaks and end up stranded or worse.
