I am looking for someone who will help me with an S280. I need to be able to understand the engine and the workings of this car.

 

Get a hold of a Mercedes service manual. It is the best tool in your toolbox. See the links below in my signature file for sources.


What do you want to know specifically about it?

Old European cars are nice, but be prepared for a lot of quirks and high prices on parts. Fact is they tend to soak you for green when they get old. Parts are expensive and things break after a number of years.
