I with blackmercedes on the 1992 300E in that it is the last year of the M103 in the W124 chassis.

I wouldn't necessarily avoid a 1993 300E (3.2) / 1993 300E 2.8, 1994-1995 E320, but I would make sure that the head gasket has been replaced to the updated style and that the engine wiring harness had been replaced.
