1965 Austin Mini Cooper S Mk 1
- Engine
- 1,275cc

A 1275cc Cooper S, built in February 1965 and finished in Tartan Red with a black roof, delivered new to Mylchreests Motors on the Isle of Man. At some point it was prepared for tarmac rallying, receiving a Stage 4 engine built by Manx Racing Developments, close-ratio gearbox, limited-slip differential, and full roll cage. A subsequent owner carried out a thorough nut-and-bolt restoration, returning it to original colour while retaining the competition specification. The odometer shows just 3,469 miles, consistent with a lifetime on the island.
