The days/weeks of sub-zero temps in MN with only a small Toyota 4 cylinder engine... I fondly (sic) remember the days of sitting in the vehicle for 20 minutes to get it functional. By the time the engine warmed up enough to thaw the transmission, your windshield was defrosted (inside).
Thank God for fuel injection and synthetic oils ( I was too poor back then to afford fancy synthetic oil).
LOL... ahhh yes!
One winter I used an old wood hauler 70 Chev K10 pickup. Damn thing was the biggest rust bucket... cab corners gone, couple of holes in the floorboards and no heat or defrost. You really had to dress appropriately to ride in that thing.
A frosted windshield was a constant companion but it could sure plow through deep snow with the skinny snow tires it had.
