Hard to say.
I had no room to display mine.
So I got an idea.
I would go down to my local Wal Mart, and look and ask for empty Hot Wheels sidekicks.
These are the blue cardboard boxes that holds 36-72 cars in them, 3 across, and about 7-9 down.
About 6 cars deep or so.
They are made to hang up on the endcaps of the isles in the toy section of the store.
They pretty much just throw them away.
I have 7 of them, with only 3 filled up so far.
Just line them up against the wall.
It's my other scales (1/24th and up) that I do display.
I don't even have room for my trains.
Good luck with all the stuff you have to do.
