The insurance should be in the name of the grandparents with the grandson listed as the primary driver of that vehicle. If all parties live in the same state this should be easy if they don't, well then that complicates things somewhat. For instance I own a vehicle that my Father-in-law keeps at his place and he is the primary driver.
The vehicle is insured on my policy and he is listed on my policy as the primary driver. Doing this way keeps the state happy and the insurance company has full disclosure of all drivers. I would also have the grandparents write a letter giving the grandson full permission to use the vehicle.
This should keep the police from thinking the kid stole the car especially if the last names are different.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
