Hydraulic suspension is REALLY Nice, but a real PIA. They tend to leak down with age and are expensive to rebuild. Same thing as used in the W116 and earlier cars. One of the budget killers for owners of the 600 Pullman limo. But if you own a 600, you have more cash than you know what to do with.
The electric motors can get tired. You need to pull the door panels to gain access and lube them as well as cleaning up the window tracks so they slide easier.
Antenna motor working is a good sign. You may need to pull the unit out, open the case and see if the antenna pigtail failed. You can feed a new pigtail in and it should return to working. I helped my kid make that fix to his W140
The turn stalk wears out the bump that holds it in position with age. You can unscrew the unit from the steering column, then using a very small round file, you can cut a deeper notch. Really easy task, but you have to go slowly and test often so you do not make it too deep a detent where it does not cancel when you turn or have to yank it back to center.
Original paint should come back pretty well. Your full detail attack may just do the job. I had to do a rather harsh route with the w140 that has severe sap damage on horizontal parts. We started with 1200 grit and worked up to 1500 to get past the oxidation and sap pitting. Then we used cutting compounds and polishes after washing and clay bar on the paint. Finished with a glaze and wax. The shine is exceptional now
