I quite driving one of my 240s when it required two glow cycles and the starter plus a good sized hill if the air temperature was below 10 C (50 F). The block heater is big help. In my experience, more glow and less crank seems to work best. But as summer turned into autumn, and daytime temperatures stayed below 15 C (60 F), I retired the car.
