for the ATCC in 1973, Moffat's Boss 302 Mustang was no longer eligible for that series. Moffat ran the Mustang in Sports Sedans in 1973 and 1974, though he refused to follow the trend at the time of moving the engine back in the cabin, later stating in a 2004 interview he "was never going to contaminate such a jewel", though he did replace the bodywork with fiberglass to avoid damaging the cars sheet metal. Following 1974 Moffat sent the Mustang back to Bud Moore in America where it sat for sale until 1995 when it was purchased and restored by Queensland based entrepreneur David Bowden (who other than himself and his sons has never let anyone other than Moffat drive the car, even turning down a request from the late Ian Geoghegan). The Mustang was voted the most popular 'Muscle Car' ever to race in Australia by readers of Australian Muscle Car magazine. With Ford Australia pulling out of motor racing after 1973, Moffat competed as a privateer through the 1974 and 1975 seasons. He was only moderately successful in the Australian Touring Car Championship races, placing third in 1974 with two round wins and undertaking a limited campaign in 1975. Other wins included the 1974 Sandown 250 and the 1975 Rothmans 300. He failed to finish the Bathurst 1000 in those years. On 21 March 1975, he enhanced his reputation as an international class driver when he drove a BMW 3.0CSL with West Germany's Hans-Joachim Stuck, British driver Brian Redman and American Sam Posey to win the 12 Hours of Sebring for the factory-backed BMW Motorsport with many considering this win to be the 3.0CSL's crowning achievement in racing. Moffat returned to drive his XB Falcon GT Hardtop full-time in the 1976 ATCC and won his second title. This occurred despite the setback of a transporter fire which destroyed his race car with several rounds left to run, forcing Moffat to borrow a car from rival John Goss for two rounds. Moffat also won the inaugural Australian Sports Sedan Championship that year, driving firstly a Chevrolet Monza and later a Ford Capri RS3100. He failed to finish Bathurst again in 1976 despite taking pole and leading comfortably with co-driver Vern Schuppan. Moffat re-established his dominance in 1977 with a two-car factory-supported team under the Moffat Ford Dealers Team banner. He won his second consecutive ATCC title in 1977,
