I loved the idea. I would make it a tiny bit smaller, though, to keep some margins in the flat space.
Also, just a curiosity: is the material resistant do heat? I imagine it gets pretty hot in there, right?
Does anybody know where to find good miniatures of the Mustang, all generations? I would love a collection with 1:43 all cars, but I can't find a manufacturer making them.
I would settle for 1:24, by the way.
Anyone got any ideas?
