How much could I get for my 1987 cutlass supreme coupe oldsmobile?

I have a 1987 cutlass supreme coupe oldsmobile that his been sitting in my yard for over 15 years. I know it would take a lot of cash to fix it up but I know i can get the engine running at least. It is a 5.0L V8 4BBL Carb. w/t roof. And someone said the bumper on it was unique along with the engine. Would I get more money if is sold parts or the car in general?|||Sorry man but you got to find someone that whats it. If its sat for 15 years lots of rust%26amp; gunk in the old girl
