Only 8,583 DeLoreans were manufactured in 1981, 1982, and 1983: 6,539, 1,126, and 918, respectively. Of those, about 6,000 are believed to be in circulation - a few hundred of them outside the United States. Many have been squirreled away in garages by those interested in the cars' future value; its scarcity makes the DeLorean appealing to those who invest in exotic cars.
