Yeah, I have 3 friends+young families with Subies, the in-laws have a '95 Legacy wagon in the fencerow, and there's an '02 Outback sitting outside my shop right now, and I'm a little skeptical if Subaru is *quite* all it's cracked up to be, over decades and a few hundred thousand miles. If you're interested in keeping one well maintained it seems the gearboxes all need fluids changed frequently, parts aren't necessarily cheap (IAC valve for the Outback is $300!!!) or readily available, head gaskets on a lot of the engines used in recent times - maybe not a worse/more expensive car to own long-term than a W123, but no better and heavier on complex repairs than straight-up maintenance the W123's need to stay solid.
Peugot? Ehhhh, not sure I want to dive THAT deep into the Euro wagon hole yet!
