Let's see. In 1967 I was being paid $.90 per hour, so that was about $36 per 40 hour week, less one third for taxes (been approximately that my whole life), means about $24 take home. So a refinish took one half weeks take home pay.
Dad used to talk about the first new car he bought. A Ford that cost $855. He worked all year that year in the cotton mill, and his W2 had his income listed at just over $1,000.
He said it didn't matter what number you put on it, a years work in the cotton mill would buy a pretty nice car.
I suspect the costs are about the same today, actually. (If you could find a cotton mill still running in NC.)
