Ford hosts $4m party as Holden workers vote on future The Ford Mustang is set to return to Australia. Ford and Holden have always been mortal enemies but at 1pm on Tuesday they will be at even greater odds. Ford will host a $4 million party in Sydney to launch the return of the iconic Mustang and reveal a sneak peak of the last Falcon - at the exact same time as the future of Holden will be decided in a solemn vote by factory workers in Adelaide. Ford has booked out two sound stages at Fox Studios and invited 1000 dealers, VIP guests and the media for its biggest ever event in Australia. The public isn't invited but Ford fans can watch a live webstream. The $4 million spend for the two-hour blockbuster is more than double what it would spend on a motor show that runs for 10 days. Ford is taking the unusual step of revealing up to 12 top-secret new models - some of which won't be in showrooms for at least three years - to reverse the perception that the car maker is leaving Australia when its manufacturing facilities close in 2016. In a rare about-face Ford's global head of sales and marketing Jim Farley - who has been tight-lipped for two years when asked by media about the future of Ford Australia - has flown to Australia to reveal the company's secrets. "There is a group of people who completely understand that Ford is staying and only our factories are closing, but there are others who believe Ford is leaving in its entirety," said the boss of Ford Australia Bob Graziano. Ford has been in Australia since 1925 - and will have an historic Model T at the event to underline its longevity in Australia, as well as a preview of up to dozen new models. The Ford Mustang due in Australia in late 2015 or early 2016 will not be revealed until next April at the New York motor show. But Ford is expected to confirm its comeback almost 50 years after the first factory-built right-hand-drive Mustang arrived in Australia. Ford says it will increase the number of models in its Australian range by 30 per cent between now and when the last Falcon rolls off the Broadmeadows production line. "Ford vehicles have been part of the automotive landscape in Australia for almost 110 years and we have manufactured here since 1925," Mr Graziano said at the May announcement of the factory shutdowns. We are proud of that history. Overall, we are changing, but our commitment to Australia remains strong. The timing of the Ford and Holden events continues a series of unfortunate coincidences. Holden workers were due to vote last Friday but it was delayed, creating today's clash. When Holden unveiled the new Commodore to the media in May, Ford announced it was closing its factories.
