I'm a hobbyist mechanic and I absolutely love how simple older vehicles are. There's one wire for each thing. The door doesn't need it's own computer module like modern vehicles...

In my newest vehicle (a Ford truck), I pulled the fuse for the cellular modem, since I don't need the manufacturer tracking my every move. Checking my tire pressure or fuel level from my phone is not a feature I care about. Remote start still works fine with the key fob.

There's getting to be fewer and fewer new vehicles I would even consider buying because of all this interconnected nonsense.
