Arrow Preventative Maintenance- 130k

Just purchased a 13' S550 with 130k Miles on it. Cosmetically perfect, but needs a few things.
I scheduled:

-Water pump
-Engine mounts
-Rear Trans Mount

Is there anything else ya'll would suggest we check on, replace, or look at for preventative maintenance?
Had to get it towed yesterday due to water pump so I want to be sure!

Thanks!

ALL fluids.

Front suspension lower arms if they’ve not been done. Front upper control arms if bushings are worn or just upper ball joints.

How is that A/C compressor? Alternator? Easy to do while doing a water pump.

Look closely at water and oil lines to the turbos.

That should get you started.

air tragic - 3 x level sensor links
trans fluid

While you are doing that water pump, also check and consider replacing the belt, pulleys, and tensioner. Very inexpensive parts and you are already heavily into labor cost with the water pump replacement. And as others have already said consider front suspension control arms and ball joints carrying the heavy weight of the car, and monitor ABC if so equipped with accumulators and filter and fluid flush.

Do the maintenance regularly, and the car can run forever..
