Windshield wiper transmission...
My sister's 92 300E 4matic's wiper transmission just got replaced at a cost of $800 dollars. ($600+labor)Maybe this is the reason why the 2001 C class have the double wiper arm system. Pretty expensive part. And I was balking at a $650 dollars part for the A/C high pressure hose of my 190E -16.
Just my .02 cents.
