Congrats! I think I saw you in an earlier thread about about disabling data-narc'ing mechanisms in cars but if not, you could post your specifics here with computer-privacy tags and I bet you'll get good advice. (For recent Fords, you just pull a fuse from the fuse box.)
I go to the West Coast -- where they don't use salt on roads -- a couple times a year, and cars last forever. I'm still driving my 1996 Camry, which doesn't even have a key fob much less a tattletale modem. (I got it undercoated here.) I would happily drive back good, pre-IOT cars for Vermonters for, I dunno, $2k?
