Description
This information guide has been written to share the history, information and specifications of the final iteration of the original Cooper S – the MKIII. Announced in November 1969, the MKIII as its name suggests was a new series in the mini range, introduced a new body which incorporated many changes, but retained the overall shape and appearance of the original classic.
The MKIII Cooper S is a particularly rare variant with just 1,570 units believed to have been built. The MKIII lacked some if the aesthetic differentiating factors that applied to earlier Cooper S variants, and was watered down in appearance so much that it could be easily mistaken for a standard Mini 1000 of the same era without looking closely.
With British Leyland’s rights to use the “Cooper” name ending in mid-1971, the writing was on the wall for one of the most successful sports cars of all time, and the MKIII was the last of the original Cooper S legend. This guide is intended to outline the main features and specifications of this rare and exclusive Cooper S variant.

Production period:
Production of the MKIII Cooper S commenced in March 1970 and ended in June 1971. Vehicles were built at the Longbridge plant in England, or exported as CKD kits and assembled in overseas markets. At the time, the cost of a new MKIII Cooper S in the UK was £942.00.
Production numbers:
1,570 units are believed to have been built. This number is based on limited production records available through the British Motor Industry Heritage Trust.
Unfortunately, it is not possible to date production changes accurately because there are no records of commission numbers for the individual cars. However, there were very few changes made to the MK3 throughout its short production run.
