I have lots of photos from the 1980's 'Metro Challenge' years from when my brother Steve Bell was Chris Tyrrell's race mechanic.
Chris was a former Mini Se7en Champion who switched to racing Metros for a few seasons before returning to Mini 7. The Metro Challenge replaced the previous Mini 1275GT Challenge race series and was sponsored by Unipart.
I will post more photos in this thread over coming days and weeks as I sort them out from my boxes of old photos
The Metro Challenge Mini Moke - Support Vehicle.
