Numerous redesigns also meant that the final design of the Marina was rushed, as the project's final deadline grew near. The car went from design stage to production in just 18 months. Consequently, the board decided to cut costs and abandon Macpherson struts in favour of an old design from the Morris Minor. They also abandoned a project to design a new 4-speed BMC gearbox. As a further cost-cutting measure the coupé version of the Marina would now use the same front doors as the saloon version. This produced significant cost savings in tooling and assembly, but left the coupé as obvious styling derivative of the saloon rather than having a different, more sporting image as Roy Haynes had originally proposed. This made it impossible to pitch the coupé as a superior product, and so it was decided that the 2-door coupé version of the Marina would be the cheaper of the two body styles, with the 1.3-litre model directly replacing the entry-level 2-door version of the Morris Minor and competing with the 2-door saloon versions of the Ford Escort and the Hillman Avenger.
