2007 SL65 preventitive maintenance
I have a 2007 SL65 with 87000 miles. I've owned it for about 6 months. I got very little maintenance records with the car. Everything works as it should right now other than probably
flat spots on the tires that I will change in the spring. Front and rear brake pads and rotors have been changed along with drivers side coil packs. I just poured a concrete pad and have a 2 post lift on order.
I also have an SDS.
Some things I would like to do as preventative maintenance are: Motor mounts, transmission mount, ABC accumulators, high pressure hose, pulsation damper. ABC flush and 3 micron filter. drive shaft flex joints. spark plugs, both coil packs
(even though 1 has been changed already). Akebono ceramic brake pads to reduce brake dust. There is also a rubber weather strip at the bottom of the rear windshield that has started some wrinkling that I want to change. And possibly valve cover gaskets.
Are there any other things I should consider while I'm at it?
I will add that the car has had all the recommended service done at proper intervals according to the car fax.

You have the major item covered in your list.
I would look at the inboard front suspension bushings, as they are likely worn or torn.
Are you sure the trans fluid has been changed? I would change it if you don't know.
Might be a good time to change the power steering fluid too.
If your shifter has not had the park lockout plastic lever changed, I would do that for reliability.
Not sure if the SL65 has issues with the crankshaft position sensor, but it's another item that frequently fails on MB, and good to replace.
Check the roof drains to make sure they are all clear.
Probably a few things I missed.

If you are going to do the engine mounts, you’ll have to drop the engine so be sure to do the turbo coolant o-rings at the same time.
Make sure the intercooler circuit is functioning properly.
The coolant in the intercooler circuit probably also needs to be replaced, mine was super nasty. You need special equipment to do this yourself.
I would also consider replacing the trans fluid and making sure the trans connector is not leaking.
Another thing to consider would be replacing the shifter lockout with the aftermarket metal piece to prevent the shifter getting stuck in park.
