In January, 2013, BMC Classics completed a complete, nuts and bolt, rottiserie restoration of a 1956 Austin Healey 100 BN2 Le Mans. Being a "Le Mans", it has all the correct "M" spec dealer installed Le Mans performance upgrades. The car has all matching numbers, and was originally Healey Ice Blue Metallic.
The Austin Healey 100M Le Mans "factory-built" sports cars were produced between September 5, 1955 and July 16, 1956. According to factory records, only 640 100 "M" cars were produced.
Cars converted later with "M" spec Le Mans modifications are referred to "Dealer installed Le Mans" modified cars. The "Le Mans" modifications first originated with four BN-1 "special test cars" that were prepared by Donald Healey and Roger Menadue for racing in the 1953 Mille Miglia and the 24 hour Le Mans of France. These were the very first Austin-Healey 100 race cars prepared for international road racing, appearing even before the 100S model. They were the prototype to the 100M.
The "Le Mans" Conversion Kit was first made available in 1954, before the start of the BN-2 production run. Several hundred kits were sold to modify cars throughout the late 1950's. Such converted cars were the plan of Donald Healey, who fully expected owners and dealers alike to convert cars and benefit from the improved performance, appearance and value made possible with the "Le Mans" Modification Kit. The Le Mans modifications include:
