Greetings to everyone after many months off this forum

My W124 is going to retire after a short but adventurous career in our household, it will be sold next month and replaced.

The next in line will be a superb example of an E320 Elegance 4Matic from 2001, in blue-gray metallic livery. The negotiations had been concluded and paperwork is under way. It has the following features:

- M112 V6 engine;
- 5G-Tronic automatic transmission;
- dark-grey leather interior;
- Xenon headlights;
- on-board navigation;
- ABS+ESP;
- 18in wheels;
- "power everything" seats, mirrors, windows

I would like to know which are the weak spots of the model, what to expect and which maintenance is to be performed (and what consumable items such as fluids to use).

Thank you,

~Nautilus
