Hi Christa:

stay a way from it! those cars were noted for head gasket failures. expensive repair especially if it overheated enough that it may have damaged the cylinder head.. Yes it may have needed a thermostat at one time and it may be the cause of the over heating or not. Juat a word of advice find another car stay away from this one.  Good luck :)
