I had an old Fiat which was a delight to repair. You could tell everything was designed to be easily accessible for quick and easy repairs with basic tools or even tool-less. Air filters were just held in place with clips you can undo in 2 seconds and swap them yourself. Now I own a modern Fiat and the filters are bolted down with custom screws and even the user manual tells you to visit your dealer to ... replace your air filters. Sorry, but fuck off Fiat! That's the last time I'm giving you my money. I hope the EU fines your greedy ass for these deliberate anti consumer designs. Though I would expect Italy to veto any such moves.
It's no wonder that some of the most desirable second hand cars are the one build around the mid 2000's as they have enough electronics for safety and comfort while still not having enough planned obsolescence built in, being reliable and cheap and easy to repair.
Modern cars are becoming an expensive subscription service rather than something you own and it seems like the big German brands are leading the pack.
