1995 E300D w124: Buyers Guide?

[Ian White]

Hello:

After a few years out of the Mercedes diesel game, I'm thinking about purchasing a 95 e300 diesel with the OM606 N/A. I was hoping you could provide some information on w124 model specific things to investigate.

The particular car has 187k on it. https://portland.craigslist.org/clc/cto/d/1995-mercedes-benz-e300-diesel/6487325490.html

I know of monovalve issues, wiring harnesses, glow plugs and leaky return lines and delivery valve o-rings.

I'm going to look at the car in Portland, ORE tomorrow. Anything I should test / look out specifically for?

(I've owned several 617 diesels in the past)
