Ferris Bueller Ferrari
Turns out the famous Ferrari from Ferris Bueller's Day Off wasn't even a Ferrari at all. It was a 1985 Modena GT Spyder California, a kit car, a Ford outfitted with a Ferrari-style fiberglass body. Three were made for the film but only two are still currently in existence. The prop car values at $325-375k, which is not bad for a knock-off.
