The 2013 Mercedes-Benz C300 4Matic Sport is a moderately difficult car to maintain. Accessing both batteries may be a problem on account of their obstructed access and convoluted bracket set-ups. The engine air filter may prove difficult to change on account of its bulky size and cumbersome access. Changing the front turn signal with reliability will be incredibly challenging, as multiple different parts will need to be disconnected before the bulb itself can be accessed.
However, the 2013 Mercedes-Benz C300 4Matic Sport has its upsides. The remainder of the headlights are accessible by simply reaching behind the bulb housing, allowing for reliable bulb changes whenever necessary. All of the tail lights are located in a single assembly behind a single panel, so accessing it shouldn’t be a problem. The spare tire and jack kit are packaged together which allows for quick set-up in the event of a flat.
