Southern Cross (Marks Motor Construction Ltd)

The Southern Cross Car Australian was an automobile company founded by the Australian aviation pioneer Charles Kingsford Smith.

Production took place in June 1933 at Marks Motor Construction Ltd , Burwood , New South Wales Australia . 

The cars were powered by an air-cooled Sydney-made horizontally-opposed flat-four motor of 2340cc four cylinder boxer engine with an output of 41 KW . The vehicles had a four-speed gearbox or a option for a automatic transmission . The chassis was made of laminated wood, from which the former construction of flying machines was made.

 It is reported that a fire destroyed the last vehicle in the early 1970s, due to its laminated plywood wooden chassis as a fire-prone vehicle. Two of these automobiles each had four doors and two convertibles each with two doors. The car manufacturing was abandoned after the death of Kingsford Smith in a crash during a night flight on 8 November 1935 in the Andaman Sea.
