Yeah, just check out the "Mercedes what a car" post and the "Maintenence Nightmare" post.
Well I've got some more good news!!! My 86 420 runs like a top too! I drive it regularly long distances. At the very least twice a month I take it on 3 and 4 hour (one way) trips and then maybe another one. It idles perfectly smooth, don't know the motor is running, great throttle response when I get on it...it's right there. Hums all day long at 80mph. 180,000 well cared for miles.

Dad bought it new, now I own it.
