Right.
A mustang was something like $2700 and the radarange was $400.
An internet calculator says thats about $4500 today.
Imagine someone trying to sell someone a machine to warm a cup of coffee for $4500 today.
You would really need to question that persons fiscal responsibility. Certainly not anything a blue collar had at home.
The first night we had the new microwave oven, mom decided to try it out by "defrosting" a 1 pound "chub" of ground beef. She placed the "chub" on a Corelle plate and set the timer for 20 minutes. It was smoking well before the timer elapsed. A hard cylinder of "meat" in a pool of hot fat wrapped in melting plastic. What a mess. We learned that microwaves work very differently from other types of ovens.
