Historical:

A sedan delivery, commonly called a delivery in American English and a car derived van in British English, is a two-door station wagon with driver and front passenger seats or driver's only seat, and steel sheet-metal panels in place of rear side windows. Sedan deliveries have spartan interior trim and were used by businesses ranging from plumbers, couriers and local merchants such as bakeries as cargo vans are used today.
