Maintenance at 100k
so i'm not really looking for DIY's, just kind of advice maybe on what you all did at around 100k?
In queue i have:
Plugs -going with the NGK Lasers, heard good things about switching to iridium
Wires -just thinking oem?
Coolant and Trans service
is there any other big things i should look for or check that tend to start to wear around now? i noticed the idle on the car is rough right now, but i'm hoping the plugs will fix that. Other than that she has been very solid
any input is appreciated thanks

What are those NGK plugs? Aftermarket? I know Mercedes uses Bosch Platin from the factory. Replace plugs with what Mercedes engineers thought would be best. They are not that expensive. I just did mine and 16 plugs came out to like $90 plus tax.
Why are you replacing the spark plug wires? Don't fix something if it isn't broken. I have over 150k on my original wires and have no problems.
Do replace the transmission fluid/filter/gasket. Also, replace the transmission plug. Cheap part but if it leaks, it might result in electrical plate failure.
Check control arm bushings, ball joints, etc. Mine are starting to go and I can feel the ride starting to deteriorate.
I wouldn't not change coolant until you are leaking. At that point replace water pump too.

The NGK are iridium plugs, I have read several other MB owners saying they raised mpg and power. OE are only about $55 w/ shipping through rock auto
Again from reading other MB owners input and advice they said it was a good idea to replace wire and plugs at the same time.
Was only planning on doing filter and trans fluid but that's good to know on the rest!
I was told to do the coolant flush, that it was part of the 100k service. The fluids to do it is super cheap and I have access to all the machines to do it so it would barely cost me anything
