I have often wondered what the owners of cars do with all the info that came with the car.
In the UK it seems that most keep the Handbook in the glovebox, You will always get some keys, but not normally the full se.t And seldom the plastic rings that came with the important key numbers.
In the USA you will seldom get the handbook with the car and also the full set of keys.
What's it like in your part of the world....
