John Watson's M29 now housed in the Donington Grand Prix Collection.
The McLaren M29 is a Formula One racing car built and run by McLaren during part of both the 1979 Formula One World Championship and the 1980 Formula One World Championship. The F version was built in 1979, but ran during three races of the 1981 Formula One World Championship. It was driven by Andrea de Cesaris in all those races, with only one finish in its tenure. This car was the last of the M-numbered cars, as later in the season, the McLaren MP4/1 was readied for use in the championship, with the MP4-numbered cars still in use currently in Formula One.
