He finished fourth in the 1976 Australian Formula 2 Championship driving a Rennmax BN7 with sponsorship from Sydney based department store chain Grace Bros.

Miedecke had actually begun competing in the Ralt at the 1981 Australian Grand Prix at Calder Park in Melbourne where he qualified in 11th place before a steady run saw him finish 5th just one lap down on winner Roberto Moreno of Brazil.

Andrew Miedecke's first start in touring cars came at the 1986 James Hardie 1000 when he was to drive a Mercedes-Benz 190E imported from West Germany as part of Bob Jane's team.

The team's second car driven by veterans John Giddings and Bruce Stewart failed to finish after their Sierra suffered differential failure on lap 82.

The team had a new car ready for the Bathurst 1000 and Miedecke was the fastest Australian Sierra after Hardies Heroes in 5th place (though he would start 4th after the third Eggenberger Motorsport was withdrawn).

While the European Sierra's had the edge in straight line speed, the Oxo car, thanks to Miedecke's open wheel experience, handled better and was quicker across the top of the mountain.

In a show of appreciation for his efforts in trying to break the Shell team's monopoly in 1988, the crowd at Sandown applauded Miedecke as he walked back to the pits.

Then during Saturday afternoon's final practice session Soper (who co-drove with Mad Andy) had a 200 km/h (124 mph) spin on Conrod straight when a tyre deflated, though the English ace was able to keep the car off the concrete walls.

Their challenge ended early as the team found that the replacement turbo hoses they had used in the rebuild did not have the required aluminium heat shielding on the inside.

Andrew Bagnall, partnered by fellow Kiwi Graeme Crosby, would start tenth after failing to complete his Tooheys Top 10 runoff lap when he crashed the Sierra at Sulman Park.

Bathurst would prove to be the final outing for the team as they did not enter the season ending Yokohama Cup Group A Support Race at the 1989 Australian Grand Prix in Adelaide.

[9][10] In 2015, Andrew Miedecke purchased an Aston Martin Vantage GT3, which in collaboration with Ross Stone ran in the final two rounds of the 2015 Australian GT Championship.
