When Jim Clark won his 25th Grand Prix at Kyalami on New Year's Day 1968, no-one could have foreseen that he had less than 100 days to live.
He was at the top of his game, had won more Grands Prix than any other driver and was embarking on a new Championship season with the Lotus 49 - already a proven race winner and with a new 'B' spec version due in time for the first European Grand Prix of the season, in May.
Before that, he had two months of fun in the sun with the Tasman Cup, an eight-race series held in New Zealand and Australia, to look forward to.
