just my guess on the radio with out being there, but it sounds like your antenna is the source of the noise. the antenna (when working properly) will go up when you start the car, and will go back down when the radio shuts off. are you only getting the noise when the radio is turned on or off???? or is it when you change stations? it could also slightly point to a bad amp. although the amps in the earlier models were better than that in later ones. How many miles are on it?
As far as cup holders a w140 has no idea what you talking about. the later models had a flip out cup holder in the center arm rest, but other than that there is one in the glove box that holds a pop can perfectly, but is absouletly useless for anything else. then there are the two in the back seat arm rest. but that's it. my prevous owner ghetto rigged a little cup holder into the center console of which ill post a picture of. as cheesy as it looks, it actually works awesome, i use it all the time.
