Oxton's career started in the late 1960s, driving a Daimler SP250 in New Zealand motorsport events and in 1968 he made the move to open-wheel racing.
[3] Oxton then partnered Brock in the Holden Dealer Team in Australia's first year of Group A touring car racing in 1985 at the Castrol 500 at Sandown Raceway in Melbourne, their VK Commodore suffering engine failure after just 41 laps.
They ran strong all day, with then 8-time Bathurst 500/1000 winner Brock doing the bulk of the driving and Oxton only completing a 40 lap "lunch time" stint.
Oxton went on to race in the 1986 Australian Touring Car Championship, finishing 17th in the series after competing in three of the ten rounds in an ex-Andy Rouse Ford Sierra XR4Ti.
He partnered Australian television commentator Neil Crompton in the team's second VL Commodore SS Group A, the car in which Brock, David Parsons and Peter McLeod had won Bathurst in a few weeks earlier.
