BUY ADVICE - 2003 E320 97K
Have 2 C240s for a year-ish now and I find them predictable unlike the C230 that's prone to some issues such as a stretching timing chain, etc.
I diy my cars so I can get in there, under and above to look. I am new to MB (about a year) But I am generally comfortable performing a PPI to an extent. But E320 is a new beast to me. I would ask you guys are class/year great cars or do they have known issues that they are prone to? I just read about the M272 balance shaft issue and still reading. What type of engine does this model have and is it afffected by balance shaft issue?
At the moment I only have a cheapy BT dongle - ordering Autel all system scanner in a week or two.
For this car what would you be looking for as far as potential trouble areas? Does it have airmatic suspension? Not reading very encouraging things on that either.




SBC Brake unit is an issue, but should have a 25 year extended warranty on it.
Also leaking fuel tanks, fuel pumps, gasoline smell inside the cabin is an issue, which had a 15 year extended warranty in CA (not sure if this was covered in other States as well), so you may want to check if this was ever done as the car is past 15 years. I had an '03 in the past and mine was done 2 days before the 15 year warranty expired due to a leaking fuel pump and gasoline smell.
Other than the above, my '03 was pretty solid.
97K miles and a 3500 asking price, not sure what you all can ask for. If the car is clean and runs well, hopefully has some maintenance history, I would not hesitate.

When SBC brakes in US have extended warranty, if the car has original airmatic bags, put some money aside for replacing them.
For me paint condition on used MB is the most important part. I can fix the rest.

And balance shaft was 2006 to early 2007 so no issues here.
