Input: Question: In what year did the Ford Mustang appear as a race car in the United States? Passage:Beechey began racing at the age of 22 in a Ford Customline V8. He came to prominence only a year later when he won the Olympic Touring Car Race at Albert Park, a support event at the Australian Grand Prix meeting which was held in conjunction with the 1956 Melbourne Olympic Games. As the expense of running this and two subsequent Customline V8s proved too prohibitive he reverted to a Holden 48-215 in 1959. After becoming part of David McKay’s Scuderia Veloce team he again returned to V8s, developing a Chevrolet Impala with which he won the New South Wales Touring Car Championship at Catalina Park. He progressed to a Ford Galaxie owned by Len Lukey and was then instrumental in forming the Neptune Racing Team in 1964. He raced a Holden EH S4 as part of that team alongside Jim McKeown’s Lotus Cortina and Peter Manton’s Morris Cooper S. He subsequently developed and raced a series of V8 powered Touring Cars with which he contested the Australian Touring Car Championship and other events. The first Ford Mustang to race in Australia was followed by a Chevrolet Chevy II Nova, a Chevrolet Camaro, a Holden Monaro GTS 327 and a Holden Monaro GTS 350.
