Hi everybody,

I am thinking of assembling a box of “cheap” spare parts in the car, that will help me to get going again in a case of a breakdown. This would be for a W126, a 1987 420 SEL.
Although the car is well maintained, I just learned that the fuel pump relay is from 1989 and other non-maintenance parts are probably just as old.

So what do you think can fail and leave me stranded, that is not too expensive to keep in the car? I have

1. spare fuses in the fuse box.
2. a wire to jump the fuel pump relay
3. a wire to jump the temp. sensor so the fan will run on high
4. headlight bulbs kept when replaced with Sylvania Silverstar

OVP, fuel pump relay, belts?

Your suggestions are appreciated.
