Buuxi weedhan soo socota: Sanadkii 1969 McLaren, oo leh darawal aan isbadal laheyn, ayaa naqshadeeyay baabuur cusub oo afar-wheel drive ah, M9A, laakiin inta la diyaarinayo, waxay sii wadeen baabuurkii hore. M9A ayaa ugu dambeyntii guul darreystay waxayna u muuqatay hal mar oo keliya, oo uu kaxeeyay Derek Bell ee British Grand Prix.
