Tips for purchase: w140 Diesel

Hello everyone! Didn’t find a similar topic in the forum (perhaps just looking bad? ), so I decided to ask myself: Are there any things you should consider when buying a w140 (especially the S350 TD)? Will now exchange the current w210 for the “monstrum” w140. Since I’m not a raster and don’t want to spend so much while refueling (without giving up the comfort) my view of the w140 diesel models is Just now I have found an S350 TD in my vicinity, which I’m going to look at shortly. And before looking at it I want to make myself smart to be prepared accordingly. So, as it is said so nicely: Long speech… My questions: – Rost (the hottest topic at w210) – what does the w140 look like? – Diseases and sufferings: What are the most important things when buying? – Motor: Which km stand is critical? – Which BJ? Which year was best? When was the MoPf? – Consumption: sow if I understand, he’s keeping himself within the limits of the diesel… isn’t he?
