the princess, unlike the allegro, made it to regular production relatively unscathed and unaltered from harris's original plan. the bonnet (hood) was a little higher, to allow for taller engines, but the biggest change from harris's design involved the rear. harris had intended the design to be a five-door hatchback, but management decided that the austin maxi should be the only hatchback in the range, making that its unique selling point, and besides, they thought the princess's prospective buyers would dislike a hatchback – despite the fact that in the rover division the larger rover sd1 was being given a hatchback design. consequently, the princess received fixed rear glass and a separate boot, belying its appearance. an estate version was also proposed, but never reached production.
