What has happened to MB's warranty? On my 1998 automobile there was a "wear and tear" coverage period that covered EVERYTHING, including wiper blades, brake pads/discs, etc. It covered those parts regardless of owner usage, excepting track use.
From the MB Canada site:
WEAR AND TEAR PERIOD
The following parts listed are covered for wear and tear during the first 24 months or 40,000 km whichever comes first.
BRAKE PADS, BRAKE DISCS, BRAKE PAD WEAR SENSORS, HEADLAMP WIPER BLADE (129), REAR WINDOW WIPER BLADE REFILLS ON STATION-WAGON, WINDSHIELD WIPER BLADE REFILLS AND LIGHT BULBS.
