It was stored for about 6 years before I got it, but after a little TLC
(check bores, spin engine to get oil around the system, fill up rad with water etc.)
it started almost first time, once the old petrol (it doesn't burn properly if it's that old)
was replaced by a fresh tankful.
I had originally planned to get it back on the road (in time for the Mini 40th anniversary), but lost time/money/interest, so I passed it on. I wonder what it is today...
