I glanced at this earlier but did not have time to read the thread and respond. What year is it? They are spectacular cars but getting old and were very complex with zero thought put into reliability 30 years down the road. Engineering and build quality were top notch but there is just so much engineering that they had to lunch some of it, like the early climate control system. There were many changes in the 1996 model year, (including climate control), those are more desirable cars although the first ones were the coolest with the little parking antenna things that popped up on rear fenders when you shifted into reverse and other features.

I'm not a complete authority on this model but I did own one at one time, (1996 S500), I did some work on it and everything under the hood was pretty straight forward Mercedes of the era. Never had an issue with the engine harness, which is what goes bad on mid-'90s era MB cars. The 6-cylinder would be a little weak in this heavy model but it's a good 6-cylinder. You would want a thorough PPI from a shop that really knows and works on these cars and a big pile of service records from the dealer or a marque specialist. Good luck.
