Hello, I'm new to the Mercedes world. I just bought a 1992 E320. 2.6L.

The car runs great but it has loads of electrical problems but I was told that this care shouldn't have the "biodegradable" wiring. Is this correct? All of the electrical problems are with interior componenets.

Also, when I search for things (I need a new back passenger side window) I see a lot of results for the 300E but not many results for the E320. What is the difference and what is compatible with this car?

Can anyone guide me in the right direction?

Thanks!
