Not like I'd ever own their overpriced garbage in the first place. I've worked on them (since the 70's), they're over-hyped trash from a durability standpoint. And how they put things together makes maintenance a nightmare.
They could learn a lot from Japan, who's worst brands are far better
Allegorical, but I have 2008 Mercedes C300 (W204). I purchased it in 2017 with 90k miles and I'm currently at 190k. It's still my daily driver and overall I remain pretty happy with it.
The tl;dr of this car has been toyota-like reliability with maintenance/repairs being uncommon but more costly when they need to be done. I wouldn't assume my experience is indicative of Mercedes overall.
I'm not a mechanic but I am an engineering technician and test driver in automotive T&V
The Germans can build motors that will go for a million miles, but they can't connect 2 wires together without causing the entire vehicle to become a rolling dumpster fire. The more tech and the more options on your German vehicle, the more you are asking for pain.
