I've filled all my display spots. Replacing an existing model with a better one of the same car works out fine.

Any other new add requires rotating a model between storage and display space or adding more display spaces. I currently have 3 models in that rotation mode now.

I've already let two models creep into one of our other rooms for display but I'm trying to minimize that. Most of the time I spend in that room is playing chess against a computer program. Can't focus on viewing models while I'm doing that. :-)
