A stretched version of the DeLorean, the DMC-24 would have been a 4-seater sedan version retaining the shape and gull-wing doors of the DeLorean. Several designs were drafted. One design, a 2-door, had the doors and cabin stretched to allow rear entry and rear seating. Another design had a separate set of rear doors. The 4-door design was produced as a rolling mock-up by ItalDesign based on the Lancia Medusa concept car. The bill for the ItalDesign version was unpaid by DMC, and ItalDesign modified it to become the Lamborghini Marco Polo.
