First of all I would like to thank people on this website that unconditionally help others. Most people on this site come here for give and take and i must admit i am mostly a taker due to limited technical expertise. However, as I learn I gladly pass the info to other novices on this site.
There are however, several members on this site, I will not mention names because I will surely forget a few and dont want them to be slighted, who dont need info they are pretty much experts but they are quick to hand out help when needed, to those people and additional thank you.
Due to this site, some handiness and logic I have not spent a dime on repairs in 13 months of ownership on my 1987 300 E which is pushing a 160,000 miles.
Now for the taking

Any advice on any how to keep this car going strong? What can I clean, what fluids to use? any small maintenance that helps so i can have more truble free driving? Thanks.
