Description

Highlights

  • History known to the current owner from new
  • Engine rebored to 1,298cc shortly before being taken off the road
  • Offered as a restoration project with all removed parts included

The Appeal

Dropping the 1,275cc A-Series engine into the Mini finally made the little Cooper a proper giant killer. In this specification, Paddy Hopkirk ran rings around bigger machinery to nab the overall win on the ‘64 Monte.

In the same year as that incredible win this Mk1 Cooper S 1275 left the works. Chassis records indicate that it is car number 460 of around 3,000 built that year, making it one of the earliest remaining survivors. The vendor says it spent its first three years as a demonstrator, then had three subsequent keepers. The vendor acquired it in 1979, telling us that he new the previous keeper because he worked at the garage he used to maintain it. The engine and gearbox have been replaced, with the latter rebored to 1,298cc before the car was stored.

Now offered as a restoration project, the car has been partially stripped, with the offside front wing. Some parts, including the front windscreen, have been removed and are included. The owner is unable to complete the work personally due to illness, presenting an opportunity for a new custodian to take on a Cooper S with a genuinely traceable history and bring it back to life.

The vendor says:

“I love everything about it, and still think that the mini is one of the best cars to drive. If I hadn’t been struck with this illness, I would have got this car back on the road myself.”
