Mercedes-Benz has gone winter mode, and by that I mean changing tires. Now, the ad is pretty low-key offering 4 tires for the price of 3. An unusual move from a behemoth such as Mercedes. But desperate times call for desperate moves. So I guess even the high-end Mercedes customers need to be enticed to change their tires what's with the financial crisis hitting everyone left and right - yes, even at the upper echelon of society. In a smaller font though, the service is available at their Thoum Service Center and - in case you didn't know it - only valid for Mercedes-Benz vehicles.
