I am fortunately in my home that I have a seperate dedicated room to my TF and model cars. The room is usually locked!
The only cabinet I have in other parts of the room is the lounge room that holds my V8 Supercar boxsets.
I have other V8 Supercar related memorabillia.
I have about 400 * 1/43 cars (size of hand) and about 100 * 1/18 cars (size of a 30 cm rule).
