Sir Laurence Hartnett Makes Plans For An All Australian Car
In 1936 Larry Hartnett began planning the complete production of a "wholly Australian car", however another World War intervened, with the (Menzies) government of the time putting these plans on hold. After the war the Government asked for proposals from any local company for production of a complete car - and General Motors Holdens were the only company to reply.
On September 20, 1944 Sir Laurence Hartnett and Mr Jack Horn of General Motors - Holdens made a presentation entitled "Australia - GM's Performance and Results - Manufacture of Complete Motor-Cars in Australia" to the Executive Post War Planning Committee of General Motors in New York. This meeting gained approval in principal for GM-H to commence the process of designing and building an Australian car.
