Rob Roy is one of the oldest and longest - running hill climbs in the history of motor sport. It attracts what may be called classical historic - or at any rate old and interesting - sports and racing cars. 
Its location is in the Christmas Hills in Victoria - an hour's drive from the city of Melbourne. 
The 5 oldest cars at the event covered in this story were classified as Edwardian. (Model T Fords from 1915 and 1917; a 1919 Sunbeam, and two 1918 Vauxhall Type D.)
Featured in the entries list also were: Austins, Alvis, Bentley, Bugatti, Ford, Frazer Nash, GN, Lagonda, MG, Morris, Talbot, Triumph, Riley, Singer and Vauxhall - ranging from 1923 to1965, 
What was also important was the presence of other magnificen machines owned/driven by spectators passing through the turnstiles. 
(Actually, the word "turnstiles" is a euphemism for paying your entrance money to the bloke at the little tin shed on the entry area)
