300E maintenance schedule

[joshhol]

I hope to be looking for a 300E sometime in the near future. I keep going back and forth between the 80's and early 90's ones for various reasons.

The question is, what should I look for on the service records that SHOULD be done according to the mileage of the car?

In other words, what regular maintenance needs to be done on a 300E between the miles of say, 120,000 and 200,000?

Also, is there any way to check the condition of the evaporator? (beyond the obvious) How often do they fail?

Thanks for the help.
