About twenty years ago I was at a car show and a vendor had one of these. I thought it was the coolest thing ever, but alas…. I was broke. It haunted me for years and once the internet became a resource, I started researching and learned a bit about it. Turns out that this German company made fleet truck chassis, mostly for school bus and delivery fleets. If you bought a fleet order, they made you buy one of these demonstration models to use to train the technicians. EVERYTHING on it works, even the engine runs, clutch and tranny synchro’s, lights… everything. I marvel at the complexity and skills needed to make it. One day a few years ago I stumbled into this one on Ebay, and grabbed it! It sits in my office and has begun many interesting conversations, plus it helps my kids understand what I do!
