Glove box hinges, the center console armrest, and the cup holders break.
The engine wiring can degrade because the insulating material falls off leaving the bare wire exposed. This can cause many problems depending on which wires are exposed and what they touch.
One or more door windows may stop working due to a failed window regulator. Replacement of the failed regulator will be necessary to correct this concern.
Other than a defective motor, a bad switch or blower motor resistor assembly can cause an inoperative heater blower motor.

1999 Mercedes-Benz S320 Reviews
Very comfortable car seats and ride for any distance.
Only problem I had is the dealer not having good mechanics to evaluate basic repairs. I am trying other mechanics though the dealer is walking distance....
I love this car ride. I would like to give it a new paint and take off any surface rust and keep it for ever...great 6 cyl. engine...great seats....runs on SUPER...
really good cars,just replace wear items and it won't let you dow.Want to beat 500s,its easy with a NOS Sniper nitrous 125 wet shot kit. My track times sor far 10.64@ 96 mpg.
My 1999 S320 is not as stylish as my W109 3.5. My S320 has electrical, airconditioning and drive train issues. Its simply becoming a pain in the neck. I wish Mercedes Benz can build an S class just like the W108/W109 and install a more efficient 8 cylinder engine. Nothing can be better than a W109 S class Mercedes Benz!
Best car ever. Perfect for everything and everyone loves it.
