70 years of the Aoraki Mount Cook vintage car rally

The Aoraki Mount Cook Vintage Car Rally is winding up after a long weekend - it's 69th year on the motoring calendar since it began over Labour Weekend in October 1956. The rally has been run every year since by the South Canterbury Vintage Car Club. The South Canterbury Vintage Car Club was formed in large part to the energy of Geoff Mehrtens rounding up friends and local car enthusiasts, and this weekend Geoff's son David is behind the wheel of his dad's last car - a 1924 Delage - for this weekend's rally. Susana speaks with Geoff's son, David.
