I have had my Mini One from new since April 2008. I have always been impressed with the quality of build. It has clocked up just under 70K, and the query I had which has already been answered about cam belt, which I now know is a chain.
The best adventure I have had so far in my Mini, was when we did a charity run down to Le Mans race track. There were 14 of our company mini's, which we do actually own, raising funds for a charity in India.
That was the first rally we held, but since then there have been lots of UK & Europe rallies. They all create lots of fun and new friendships.
