What an absurd machine! I like!
Funnily enough I made a model of a 5 wheel car a few years ago... one of my inventions required 8 plastic kit car models in various stages of assembly, and Airfix kindly supplied 8 model Aston Martin Ulsters (a 1930s sports racing car which looks a little like the old Bentleys). Of course, I had a lot of left-over parts, so using them and the sprues (the "framework" which the plastic parts are supplied on) I concocted an absurdly gorgeous car with 4 front wheels and one rear. I put lots of headlights on front and back, lots of exhaust pipes and all many of extras. Down near Bristol I once saw a 9 wheeler trike, at its rear it had two 4 wheeled truck axles, and a single front.
