I tend to "life" parts to prevent unforseen breakdowns, this is something you should be familiar with through the "air" portion of your screen name. . . There is a bell curve where a few parts fail at low time , most fail at some mid point and a few go nearly forever.
The choice is to have the car down on a schedule to head off likely failures or wait for things to break leaving you stranded. My 40 years in and around the car business tells me to fix things before they break.

The 2000 C class W202 was never offered as a manual in the US.
In some cases MTBF is dictated by how the car is driven ( trans bearing ). In other cases ( fuel pump ) there is an absolute upper limit to pump life that lack of filter changes will only reduce.
There is also the decision to change a low cost part to prevent damage to high cost parts, the trans bearing is an example of this.
The fuel pump is an example of a "leave you stranded part" that gives little / no warning before failure. Change this type of part and your stuck on the side of the road events will be minimal.
