Do you think a 1982 Volvo 240 S with 192,937 and a price of $1500. is a reasonable car to get for my 21 year old son living in Vermont?

That's a roll of the dice. Any car, and Volvo is a well engineered car, but pushing 200k and 33 years it could go another 50,000 or become a money-pit from day one. I realize that answer is not much if any help, but it's just too unpredictable

I was worried about that. I unfortunately just traded in a 2009 Impala with 90,000 miles that was running into constant repair problems but at least I knew we were the only drivers.

The engine and transmission in the Volvo will probably run forever, but everything else (A/C, electrical, fuel injection, etc...) will need constant attention and lots of money. If it has any power accessories (windows, cruise control, sunroof), then RUN from this car.
