I must admit to feeling slightly apprehensive as Sir Stirling Moss was gingerly helped into the driver’s seat of the Mercedes SLS.

I was already in the passenger seat, wondering whether a man who had recently suffered two broken ankles would be capable of piloting the SLS up the hill at breakneck speeds.

I needn’t have been. He may be 80, but Stirling’s as sharp as ever. After opening up the SLS between some railings on his way to track (ignoring the take it easy plea of the marshals), Stirling made his way to the bottom of the hillclimb to wait to be beckoned to the start line.

On our way we passed Derek Bell. Stirling cheekily told him to stop “posing” in the open-top Bentley Supersports.
