I am living proof this "collecting to sell later" thing doesn't work. In the early '80s I started collecting a certain manufacturer's 1/24 scale NASCAR and Sprint Car kits. I bought 4 of each. One to build and three to sell. The only reason prices have gone up is because the prices of new model cars are more. Only a few very limited editions are worth much. Now I'm going to try to sell them in complete lots. They take up ALOT of space !!! I'll make a little profit, but definitely not what I pictured in 1982 !!!
