I have an accepted $400 offer on a 1991 190E gasser as a parts car. Needs a head gasket. 2.6 with 280,00km. It is in much better shape than my '86 190D diesel. Kinda wonder if I should really part it? Maybe I should fix it? any thoughts?

I could really use a lot of parts from this car, exterior parts, interior parts, electrical parts. I think some of the driveline may even be the same.

Would I make any money fixing and reselling? Could this car be anything special? It has been de-badged except for the stars. How do I tell?
