I had a 1969 Volvo 144. This was in the days before heater rear screens and when you set the ventilation to demist, as well as it going to the windscreen the warm air went along through the sills (keeping moisture at bay) and up to vents below the rear screen.
It also had front and rear crumple zones, disc brakes all around and dual-circuit brakes (two front and one rear).
Engineering wise it had a pair of auxiliary drive belts (so if one broke you were not stuck and a thermostat that didn't just open and close but when the engine was cold, directed the water flow around the exhaust valve stems for rapid heating.
