This is just a silly statement. Your 2007, 2016, and 2016 vehicles were all new cars in 2007, 2016, and 2016.
There are plenty of 2020-era cars that are, so far, remarkably reliable and cheap to maintain and repair. It's simply that Volvo and Polestar are quite bad at making vehicles.
To clarify, I was making two independent points and didn’t do a good job of separating them. These being:
1. It frequently makes sense to buy older cars for several reasons (cost, common problems being recognized and understood).
2. I’m not interested in anything after ~2020 or so, not because they aren’t built well, but because they include too many “features” that I refuse to own. Two-way telemetry, that sort of thing.
