By 1968, and despite increasing success in their native series, Anglo American Racers were starting to run short of funds. Development of the Eagle Mk1 was halted as the team ploughed what little funding it had into the design of its successor, the projected Mk6. Nevertheless, Gurney persisted with the older car for the first half of the 1968 season, but was only rewarded with a handful of retirements and one single, ninth-placed finish. With the obviously unreliable car also, thanks to its intricate V12 engine, being one of the more expensive cars on the grid to maintain, AAR bought a McLaren M7A. Ironically it was with the McLaren, built by his previous year's AAR teammate, that Gurney scored the team's only points of the season. At the end of the season AAR closed the doors on their foray into Grand Prix racing, to concentrate their efforts on USAC racing.
