A counter argument to your counter argument, in point of example would be any Land Rover / Range Rover vehicle. If you've owned one, then you know - at a certain point they start falling apart. It doesn't matter what model year they are. On the whole, it's a certainty (with some rare outliers that run forever). The newer model years have considerably worse repairability. I'm lucky in that my 2012 is still relatively easy to work on.

Repairing older model years _tends_ to be cheaper as there are more surplus parts as more vehicles are retired. I've never lived in a county that didn't have several junkyards.

Reliability, repairability, and durability varies greatly by year, make, and model. Newer model years do not mean that all three factors always improve, and frequently mean that some or all of those factors regress. JD Power, Consumer Reports et al run yearly technical reports on nearly every vehicle out there if you're curious.
