Hi, I inherited from a dear friend a new to me 1987 420SEL. I would like to take great care of it and make it nicer. Any concerns with adding transmission fluid? Light is on. It is low.

It didn't go for 2 years. New battery, cleaning up under the hood and now it goes. Radio (fixed kind of), door locks kind of work now, emblem on the front, and a spare key for stupidity. For awhile, it smoked like crazy and was leaking in the driveway, but those seem better.

Got brakes fixed. Next dream of AC working. But, practically in reading threads it looks like priorities should be oil change w/ new filter, gas filter, any other suggestions? Should I dare the oil change?

Will probably post pics of my new love Thank you in advance for advice!
