My first car (a 1979 Ford Escort) had a manual choke, also had to be wedged to keep it out. I also had an attachment on the keyring which was some heating device that would defrost the lock in winter (almost like a heated key).
Also car related, I remember my grandad was really into CB radio in the early 80s, he had the bendy aerial on the car, receiver in the glove box and a huge aerial in the garden
