1979 mclarenm 29

From the listing for this 1970’s McLaren F1 Car for sale:

The McLaren M29 was designed by Gordon Cuppuck to replace the large and unwieldy M28. Abandoning the previous car’s honeycomb monocque construction Cuppuck reverted to double skinned alminium sheet and pushed the cockpit well forward to enable the use of a single large fuel tank between the driver and the Cosworth DFV engine. This allowed the car to be slimmer and lighter with more efficient ground effects and improved the aerodynamics of the bodywork.

Introduced at the British Grand Prix in 1979 the M29 was qualified in 7th by John Watson who then finished a very competitive 4th, McLaren’s best result for some time. M29-2 was driven by Patrick Tambay for the remainder of the ’79 season, he was quick but did not have a lot of luck usually being the victim of engine failure.
Over the winter the M29s were upgraded to C spec and John Watson took M29C-2 as his race car for the 1980 season using it for all the Grands Prix that year.

From Wikipedia:

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 five races of the 1981 Formula One World Championship. The M29F 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.
