E280CDI SPORTS ESTATE and C200 KOMPRESSOR SE Coupe Auto (1.8 lit petrol)
I had two W210 E300TDs .... OM606 engine
Both of them great cars and mile-eaters.
The W211 E280cdi OM642 is another awesome engine.
It's now on just-over 200,000 miles and goes as well as the day I bought it on 110,000 miles.
I could complain about one or two quirky things about both engines.
BUT - Overall they have been greater performers and very reliable.
