I also have a simple downgrade path to a fully mechanical vehicle. On the Benz replace the injector pump with a mechanical one and the transmission with an older hydraulically controlled automatic or manual. Similar options available on the Toyota.
But really the "threat model" is about complexity, not malice. I'm not worried someone will try to hack my car. If they manage it, good on them. I am worried about a manufacturer preventing me from maintaining my cars. Newer cars are so tightly locked down that maintenance is unnecessarily difficult.
