I store my Porsche (and another car) in my garage with just a cover. Never had a mouse in the garage. Only thing I can think of is the fox family living under my shed on the hunt each night. Also noticed my backyard vole problem disappeared 👍🏼
Making the assumption it's under the hood and foxes, and other large critters, are not getting under the hood. You could seal it in a Tupperware bowl with a small mouse sized hole - zip tie the lid shut.
Zip tie (or other wire) some of these under the hood. They eat it and leave the area to get water and die. I use these in my attic and shed and you can see when/if you have critters by how much is eaten. I now have a fox family living on my property and have not had a mouse problem since -...
I would pick an auto body shop you know and trust and have them pay for the repair (obviously have them agree in advance). I would not let them take control of the repair...will likely be a horrible repair.
Anything worthwhile would be a new seat. I have the massage seats in my MB and they are quite impressive. As you noted, they do help on long trips - hot stone massage 👍🏼
There’s many other products developed in China that harvest data and send it back - home routers/modems/wifi, mobile equipment, security cameras, TikTok, etc. I’ve been watching the Bronco to see who it’s communicating with…more on that later.
