All general statements are false. But you really should listen to the OP. Everything about your Beech 18 is just terrible. Round engines. Too many engines to begin with. A taildragger. We won't even talk about the looks. If you can even get $15,000, you should sell it immediately. So.......will you take $20,000 for it? This list of planes to avoid sounds a lot more like a list of planes that I wish I had.
