Yep, you have wandered into a place where there are thousands just like you. If it is mechanical and old, or newer. Most of us have an interest or a collection already. Wait until you meet others face to face. Soon you will be going to visit. Then meeting more and visiting more. Pretty soon after that, new yard art will start showing up at your house.
Ten years ago I had 1 M715, a hot rod truck, a British sports car and a shop they and their parts could all fit in. Now I have 9 MV's, 2 British sports cars, a metal shop almost full of parts, a new outbuilding full of more parts, 3 more MV's at my place that aren't even mine and a couple of other vehicles from fellow addicts that are mine as well. I am a mild addict compared to others on here by the way.
Your fellow Okie, Warthog, has probably brought home three times as many vehicles in just a third of the time is one example.
The only cure is to buy more.
