Hi,
Just picked up a cheap 300e 24 valve 230,000km. Wasn't running but the car is in good condition.
The previous owner said when it broke down it started to run rough, then it lost power and would no longer run.
He didn't want to spend any money on fixing it.

Did a compression test when I got it home and the readings are;
1: 40
2: 60
3: 70
4: 70
5: 65
6: 60


Does anyone want to have a stab at what the most likely cause is before I go pulling it apart?
