What is the value of a 1982 GMC andura van?

Hard question to answer without knowing more. Are you asking because you are buying? selling? scrap? insurance reasons? etc.

Depends on how it's equipped, camperized? etc. Running? not running? rusted? etc.etc.

I'd say anywhere from $100.00 to a 1000.00 not much more than that no matter how grea a shape it is.
