Would you happen to have any of their terms agreements available?

These companies I don't know as much about. My knowledge is more focused around electronics with this issue, and how it's often an issue for doing your own maintenance and modifications (and how I've gotten these stories with Deere frequently popping up in my phone's news ticker thingy).
But, considering even Rolls Royce was able to pull some crap on someone who bought a second hand Rolls Royce, I wouldn't be surprised if those other companies have some shady legal abilities tucked away in the fine print.
