I currently have a 1985 190e 2.3 8V with 197K. I am thinking of buying a 1994 E320 with 159K. The price is $4800 and the guy just had a $1400 service (3 months ago). The car is very nice. He is eling it because he bought a Jeep Grand Cherokee and does not want 2 payments. I have requested service records (I know he had it serviced professionally, he is an idiot when it comes to car maintainence). My question is this: What are common things to go wrong with the e series? Are they the same as I would expect from my 190e? Is the heat/AC more reliable than the 190? Mine is aweful. Thanks in advance.
