For 1976, the Confederation for Australian Motorsport (CAMS) announced Sports Sedans would finally get Australian championship recognition, and a 7 round national championship was conducted. Geoghegan missed round 1, but finished second in round 2 at Sandown, behind Allan Moffats new IMSA DeKon Monza, beating the Monza in the second heat. Mechanical failures at the next two rounds brought no points, while a troubled round 5 at Adelaide netted fifth. And that was the last appearance the car made in the ’76 ASSC. Geoghegan made two appearances in the 1976 Marlboro series at Calder Park, finishing second to Frank Gardners rapid new Chev Corvair in round 3, while not making the finish in the opening round.

The car was fast, and there was no doubting Geoghegans ability behind the wheel, but the project had been a series of frustrations that fell well short of its potential.
