The painted Focus bodies move over a covered bridge to the upper level of the final assembly building.

By the late 1920s, Fisher wasbuilding bodies in every North American city where GM was assemblingautomobiles. Fisher’s plant in Pontiac, built in the late 1920s, was a showcase:the first to be connected by overhead closed bridge to the final assembly plant,thus eliminating the need to haul bodies by truck even short distances, stillnecessary everywhere else (Fleming 1983:116).

From the welding line, the bodies are transferred via an overhead bridge to the paint shop, which is one of the cleanest and most modern in Europe - in a recent survey, it was ranked third most efficient, behind two BMW operations. Doors are painted separately but remain in sequence - a separate door assembly line is situated in the main assembly hall, where door interior modules and glass are fitted, before the doors are reunited with the main body shell later on the assembly line.

The final assembly line is less robotised - this is where a large proportion of the 2,000 workers are employed. Factory workers earn around EUR900 per month - a lot less than in Western Europe.

On the assembly line, bodies initially travel on an overhead conveyor, until they reach the chassis marriage station, where the main under-car modules - front-end; front suspension/engine/transmission; exhaust system and rear suspension, are fitted. These arrive on height-adjustable skillets, and move into place on an automated 'loop', which positions them directly below the bodyshell. The skillet then raises the modules up to 'marry' with the body shell, and workers manually fasten the modules to the body.
