A beautifully and accurately restored Mini Cooper S with a rare Works 1275 engine which was originally ordered new by Appleyards Ltd of Leeds. There is a widely accepted figure in the Mini world that just circa 700 blocks were cast with the necessary internal strengthening that were then used exclusively by the Works.

The 1275cc Mk 1 Cooper S was officially launched on the 11th March 1964 and Abingdon almost from day one supported rally teams that would compete in the "up to 1300cc" classes from spring 1964 to 1970.

Early major international rallies in 1964 for the new 1275cc Cooper S included the Acropolis Rally in Greece, the 1000 lakes in Finland, Alpine Rally and the British RAC Rally. The Cooper S most famous, outright win was in the 1965 Monte Carlo rally, driven by Paddy Hopkirk and Henry Widdon followed up by their star appearance along with Bruce Forsyth onstage at the Sunday Night at the London Palladium on TV.

The restoration has just finished having been professionally set-up by Slark Racing prior to being offered for sale.

Key Elements of the Rebuild Programme from 2015 to 2023

The hours and dedication to this task were not fully itemised but it spent a good year just with me in Guildford whilst key elements were fine-tuned and finished, in the main by the ever excellent Paul Wilson. In short, the finished product is a stunning restored example benefiting from this rarely available "Works" engine.

It would be a pleasure to answer any questions you might have. However, to really appreciate this Mini Cooper, it needs to be seen “in the flesh”, so do please call me directly on 07788 865700 to arrange a viewing.
