Welcome to the W140 Benzworld Forum.
I'm one of the moderators here, and I felt you should have your own thread.
Here is the scoop, The seats:
A) If both do not move, then my guess is you have a power problem: Fuse/power to the fuse/bad floating ground. Each seat has its on power controller module, or someone took the seats to have them upholstered, and did not connect the power connector to the front bottom of the seats.
The rattle. It is serious as the catalytic converters are required for emissions testing in a few states in the USA, but you have not filled your profile, so we do not know if the converters really matter.
Fill out your profile.....
Check with your state(providing you are in the USA) as you may not pass the safety test, or emissions. The converters may be a easy fix, but may be a serious engine problem too, so understand that too.. For this to be a California car, I would run away as the emissions testing will expose that demon in the car...
Another problem with all these cars is at the moment key-fobs are not easy accessible, so I hope you get the two key fobs with the few spare keys these care came equipped with. A new key fob is around $300 to $400 each...
When you buy the car, you need to replace the heater tee as you could destroy the engine in under a minute.
I'd try to find another as these cars are in abundance on both coasts of the USA.
Alll the best,
