2005 cdi issues?

[bart_dood]

Hi Folks,

Been a long time since I was here. I used to have a nice 85 300D and ended up selling it to get something newer.
However regret it in a lot of ways now, and looking to get another benz diesel.

Wife wants something newer with more safety features, so I zoned in on the 2005-2006 E320 cdi model. I've read it is the robust straight six engine without all the modern 'bluetec' emissions equipment. Mileage seems good considering the size of the car.

I'm looking at a car with 100-150k on the clock, what should I look for? anything that blows up on these engines like bad vacuum pumps or some other weak spot?
How are the timing chains? how long before they need a replacement or adjustment (via offset woodruff key?).

Transmissions ok? any weaknesses in them? high pressure fuel pumps reliable?

Any other advice appreciated.

Thanks

Chris
