[SUBARMAN]

Taken from Wikipedia:
A wagon (in British English, sometimes waggon) or dray is a heavy four-wheeled vehicle. Wagons were formerly pulled by animals such as horses, mules or oxen. Today farm wagons are pulled by tractors and trucks. Wagons are used for transportation of people or goods. Wagons are distinguished from carts (which have two wheels), and from lighter four-wheeled vehicles such as carriages. A wagon could be pulled by one animal or by several, often in pairs.

Sometimes, the word wagon is also used for railroad cars (not motorized, for goods or passengers), and the word is a part / the usual short form of station wagon, the non-British term for a sedan (saloon) with an extended rear cargo area. Other names: estate (car) / shooting brake (UK), break (F), station sedan (Aus), Kombi (generally in German, in English also varied to combi), Variant (VW models), Caravan (GM's Opel models), Avant (Audi's wagons), Touring (BMW's wagons).

So, we would seem to drive an Impreza with an extended rear cargo area.
