That is the reason why I'm having a hard time finding a well maintained car. Every car I've found so far has incomplete records, and FRAM filters and all kinds of great stuff. I even saw bungy cords under the hood of one car!
I may not have a 2002 Benz, but one thing is for sure, I never go cheap on lubricants and filters. Always Lubro Moly, K&N, etc and always on time. My battery failed, I bought an OEM. Any part I change must be oem or better. That's how I treat my cars anyway.
