Drivetrain is the same as the 124 E320 - M104 engine and 722.4 transmission. A bit long in the tooth these days, but definately bulletproof. No wiring harness issues, but head gasket remains as a possibility. No harmonic balancer issues, that was the early M112 V6 engines.

Definately have a PPI done. The 210 does not seem to be as rustproof as the 124. Otherwise, it is a nice driving and very comfortable car.

If I could find a 124 like JimB's for $3K, I'd buy it too. But most 124s are beaters now. At $3K, buy whatever is in decent shape and was halfway taken care of by the owner.
