Presuming these known issues with the 3.2 have been fixed by this point on this particular car, are they good engines otherwise. Or is the headgasket a reocurring problem? Is this "wiring" problem dealing with the engine wiring harness? If I call on this car, I will certainly will inquire about the headgasket and wiring. Is this 3.2 the standard engine for the 300E's in '93 forward until they went to a V-6?
