Some brand new Maestro's and Montego's were delivered brand new from the factory to dealerships with hoses not connected behind the dashboards. The dealership mechanics had to go over them with a fine toothed comb to tighten up starter motor bolts, fuel line clips, everything. They were literally thrown together.
During industrial disputes, line workers at Leyland used to sabotage cars deliberately as a way of 'getting back at management'. Vehicles were never tested thoroughly prior to delivery to dealerships so they received vehicles with sabotaged gearboxes and engines that caused problems from day one. It backfired not surprisingly when even the most hardened 'Buy British Cars' brigade gave up and bought foreign motors that were reliable and worked.
It's a shame because whilst it was a rather ugly vehicle the Maestro was a very comfy car to drive with great fuel economy.
