After the two victories in 1964 and 1965, there were hopes of a third victory at the 1966 Monte Carlo rally. Timo Makinen would have won the event had he and the other Mini-Cooper team members not been disqualified on a rather controversial technicality.

In 1967, LBL 6D, a 1275cc Mini-Cooper S driven by Rauno Aaltonen and Henry Liddon, won the rally by just 13 seconds. They had faced stiff competition from the Porsche 911 and Lancia Fulvia. All five cars in the BMC team finished, the other four being placed 6th, 10th, 15th and 41st.

The 1967 event was the BMC competitions department's last moment of glory. It was closed in 1970, ending the successful era of Mini Cooper rallying.
