The Audi brand ambassador, who hails from Dumfries, was the guest speaker at the famous RAC Club in London and then headed north for the Jim Clark Weekend in Duns.
And the three-times Le Mans 24 Hours champion was delighted to participate in the event, which was organised by Club Lotus and the Jim Clark Trust, marking the 50-year anniversary of Clark’s remarkable 1965 season.
This saw him clinch his second F1 world title, win the Indianapolis 500, the Formula 2 and the Tasman Championships all in the same year.
McNish, who is patron of the Jim Clark Trust, said: “The Jim Clark Trust put on an incredible event. It was perfectly in the spirit, tradition and passion of Jim.
“I was privileged to drive one of his race winning Lotus 25’s, to sit in his seat, notch the gear lever into first gear and drive away was a huge honour.
“Jim Clark, even 50 years on from his stunning season, still inspires young racing drivers.”
He added: “The turnout at the event confirms that Jim Clark is still a huge asset to Scotland and the Borders region, and the Trust’s work to upgrade the Jim Clark museum in Duns to continue the legacy of a legend.”
