1985 Castrol 500

[1] The race was won by the JPS Team BMW 635 CSi of Australian Touring Car Champion Jim Richards, and his co-driver Tony Longhurst.

JPS Team BMW made it a 1-2 finish when their second car, driven by Neville Crichton and on-loan Nissan team driver George Fury finished only a few seconds behind.

Finishing in third place was the surprising Toyota Supra of Peter Williamson and 1985 Motorcraft Formula Ford Driver to Europe Series winner Tomas Mezera.

The 1985 Castrol 500 was the first time since 1972 that neither Peter Brock or Allan Moffat had won the Sandown enduro.

1984 Castrol 500 winner Brock, who claimed pole position with a time of 1:52.3 in his Holden Dealer Team VK Commodore SS, suffered engine failure after 41 laps, while Moffat, who was without a drive in 1985 due to Mazda not racing in Group A, was part of the ABC television commentary team.
