I have a 2001 S55 AMG, with 115k miles. I want to make sure I address any problem with preventive maintenance so I don't have any issues with it.

Anything major I should be concerned with doing soon around this mileage? Spark plugs, things like that.

I recently did:

Oil Change, Cooling system flush, new ball joints and control arm bushings for the front, and everything else seems to be good - but anything I am missing? Transmission fluid/brake flush, stuff like that?

Also..my windshield wiper fluid is always on empty because I think there is a leak - most likely the headlamp washer nozzles since they are missing. I went to Mercedes but it's almost 1k to repair this to get the fluid from leaking and replace the nozzles, any cheaper way to do it so the tank stays full? I don't care about the headlamp washers, just the windshield washers.

have you change spark plugs?...
115k... is about the right time to replace those spark plugs..

trans fluid are lifetime.. don't touch it unless there something wrong with it..

cooling flush is good but its a waste if you don't replace your waterpump..

check belts for cracks.. replace belt tensioner pulley if need..

last thing.. you can find online the washer resevior for cheap.. site like ebays.. pelicanparts.com or any site that sell oem mercedes parts. and have your local mechanic install it for you
