IANAL,

But IMO just because you are entitled to repossess a vehicle should not allow you to keep the contents of said vehicle. They are separate from the vehicle.

If you hold lein to the vehicle, you are entitled to that vehicle, but what if the handgun is a family heirloom?
I think the family is entitled to the gun.

They may not have claimed the gun because they aren't even aware it exists.
