The Australian Marinas were built from CKD kits sent from Cowley in England, but used high levels of local content, including different running gear, axle, interiors, seals, seats, uprated dampers and mounts, uprated wheels and a higher grade of fit and finish. The Marina Six used a separate front sub-frame to support the weight of the Big Red engine and different front torsion bars as well as a pair of rear radius arms in an attempt to improve handling. Base model featured a 3-speed manual gearbox – sourced locally from Borg-Warner – to meet local content requirements. The Borg-Warner automatic was, however, the variation most popular in the local market.
