Given the amount of time and skill that went into the construction of these hand-made machines, the estimated value seems ridiculously low. (If craftsmanship isn't your thing, you might be able to pick up a Cy Twombly masterpiece for under $1 million.)

Superbly detailed and engineered approximately 1.4 scale model of a circa 1905 two cylinder 'Stanley Steamer' after the original built by twin brothers Francis and Freelan Stanley in Newton, Massachusetts.

Ferrari Superbly built in Detroit by Ron Phillips and Jeron Classics, a limited edition exquisitely detailed hand-made 1.4 scale radio control Ferrari fitted with a single cylinder, fan-cooled engine made in Germany by Bernhardt GmbH, putting out 1.5 hp at 15,000 rpm and reputed potential top speed of 100 mph. Features include rear wheel drive through centrifugal clutch and driveshaft, hydraulic disc brakes, working quick action fuel intake, hand made wire wheels each with 36 spokes, semi-pneumatic rubber tires, wood-rim steering wheel and full instrument panel including working tachometer. The removable aluminum body is mounted on stainless steel chassis with full independent suspension from coil springs and tube shocks, perfectly finished in 'rosso corsa' with authentic Scuderia Ferrari decals.
