I would not buy 1993 300E because it has the new 3.2 liter M104 engine. This model should've been badged as "E320", but wasn't.
The reason why I wouldn't recommend it is because it will have a bad engine wiring harness (they were all bad from 1993-1995). It will also have a bad head gasket. The original head gaskets were poorly designed, and it will leak oil.
I'd look at 1989-1992 300E's.
