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.
Unique to Canada, the Pontiac Pathfinder is an entry-level station wagon or full sized car that was based on a Chevrolet chassis but used most of the distinctive Pontiac styling parts.
 Engines were also produced by Chevrolet, another General Motors brand.
 The use of Chevrolet-based bodies resulted in shorter front and rear fenders and Canadian specific wheels and hubcaps.
 Interior trim often was also unique to Canada.
 The last Pathfinders were built in 1958 as Pontiac's (Canada) base model.
 Body styles included a sedan delivery.
 This car was Pontiac's last full-size sedan delivery.

A panel van (or panelvan) is a form of solid (rigid-bodied, non-articulated) van, smaller than a lorry or truck, without rear side windows.
 In the U.K., this body style is referred to as a "car-derived van", and in American as a "sedan delivery".
 Panel vans are widely used in many parts of the world for transporting cargo.
 In some national usages it is distinct from a purpose-designed van in that it is based on the chassis of a family car design.
 In places where they are distinct from a "van", they have less cargo space but better agility and maneuverability, making them particularly suited for cities with narrow streets or heavy traffic.

In Australia, panel vans were a development of the Australian "ute" (utility), a variety of pickup based on a car chassis.
 In the U.K., this body style is referred to as a "car-derived van", and in American as a "sedan delivery".
 The first panel vans were manufactured locally by Holden and Ford Australia in the late 1950s, but did not become popular until the mid-1960s.
 Other foreign brands of enclosed vans manufactured or assembled in Australia included Volkswagen, Morris Minor, and Chrysler.
 Panel vans enjoyed tremendous popularity in Australia throughout the 1970s, but by the late 1980s, they began to slowly disappear from Australian roads as demand fell and major manufacturers slowly ceased building them.
