see Pierre Scerri’s fully-functional Ferarri 312 PB. 

And when Scerri says “fully-functional,” he means it: the engine runs, the transmission shifts, the tachometer reads accurately — it even starts with a tiny key.

From the Internet Craftmanship Museum, who has declared Scerri their “Metalworking Craftsman of the Year” for 2007:

“As a young telecommunications engineer [Scerri] wanted very much to own such a car, but realized there was no way he could ever afford to buy one.  If he wanted to have a car like that, he would have to build one himself.  He started with drawings of each part of the car — a project that took three years in itself working just from photographs of the real car.  He then started on construction of the car.  The 12-year construction odyssey took Pierre on a journey though virtually every process needed to build the full size car.  He learned to mold his own rubber tires, cast his own glass headlights, make his own battery, weld the tube frame, build the shock absorbers and such delicate tasks as making a miniature tachometer and other working gauges.  The drawing and machining skills were learned from reading books, as he had not been given any training in these subjects when in school.”
