How do you search for and verify one of those vehicles without a computer? Also, I haven't bought a new car in many years. Is there something like a EULA buried in the small print? And I don't imagine buyers on the secondary market sign anything. Or will it become illegal to sell used cars because the software license doesn't allow for transfer?
