On today's show we have a very special guest, "Douglas Niven".  He's the cousin of the late Jim Clark and today we get a rare insight into what it was like to know Jim Clark, back in the 60s when he was winning world championships and dominating the Grand Prix world.  We also hear about Charterhall and Winfield airfields, that were great race tracks in their day and one was the host of Scotland's only Grand Prix!  Plus Douglas talks about the Jim Clark Trust and the museum which is undergoing major work that will be completed next year and will be packed full of legendary cars, history, simulators and more.  Enjoy!  www.cardealadvisor.co.uk.  www.jimclarktrust.com
