I didn't know which section to post. Sorry in advance and moderators please feel free to move this post to the appropriate section if needed.

Dear All,
I am a new member and have been going through the forum to get information. Although I am a new member, I am not however new to Mercedes. I have had in the past several W123 diesels and the late W124 Diesels. I am however now crossing over to gasoline

I am looking to get the 1997 E320 loaded to the max with pretty much every option that was available at the time. It has been kept up very well and serviced well and has around 70K miles on it with all services performed in timely manner.
My main questions were some that I was not able to find answers to partially because of my limited computer knowledge.
I know that there were some problems that existed with the 1994-5 W124s as far as head gaskets, ac condenser, as well as throttle actuators, and the notorious biodegradable Wiring harness. So my question is whether all these problems were fixed in the 1997 E320 or not. If so, what major problems did the 1997 E320 bring along with it in its genealogy.
Secondly are all the owners of the 1997 E320 satisfied and would they recommend others to get one.
I plan on using it as an everyday driver and I drive an average of 8000 miles per year with more than half being on freeways and everyday in the city about 5 miles. I am also going to try to add a poll about satisfaction and reliability.
Thanks in advance fellow members.
Should I go for a 2000 or 2001 E320?
