Curtis Hixon Hall. Great example of the International Style. It just got old and had to be torn down. I saw my first car show there. Went to many a concert there. Took the Bar exam there. I really miss the place.
Fardier de Cugnot. 1769. First ... car ... ever. Built to pull cannons, it long pre-dates the railroad. No brakes, so it also had the first auto accident ... banged into a wall at 2mph! Cugnot had to flee the French Revolution in Holland, later he was brought back to Paris and properly feted. This replica was built for a 1930 French movie. You can see it at the Tampa Bay Auto Museum.
Bohn Aluminum had dozens of futuristic magazine ads published, predicting aluminum use in all sorts of futuristic motorized machines, from cars to combines. This is a single example, but you can find dozens on the web, each an almost lurid view into a gee-whiz future where even the most mundane machine can look like something from "The Jetsons."
Stout Scarab. Former Packard man William Stout essentially invented the minivan, and he had Tjaarda design it with a Ford engine in the rear. The $5,000 price point meant that only a handful were ever built. Passengers could sit around a central table and nosh or play cards.
1982 Cumberford Martinique. Bob Cumberford wanted to build the ultimate neoclassic. Not content with simply dropping a fiberglass body on some ordinary Detroit chassis, he engineered his car from the ground up, and included a BMW engine and Citroen suspension and steering components. The car made copious use of real mahogany outside more than inside. Like the Gaylord Gladiator its price doomed it. The most grinding postwar recession up to that time didn't help a bit. Only two were built.
Aston built an entire factory to build just 77 of these bespoke beauties, called one-seven-sevens. 50 would have been too few, 100 too many, and 75 too predictable. If you have to ask the price... Oh, and if you buy there is a multimedia presentation with special effects as they unveil it for you.
The Tata Nano. A real car for $2,000?! Impossible! Originally conceived as more of a motorized golf cart with side curtains, iterative redesigns over a ten year period yielded instead an actual people's car without sacrificing any of the essentials. At the other end of the spectrum, India's Tata now owns Jaguar.
