Extremely accurate description of what happened to my 1994 S320
Not complaining, The '99 S320,6cyl. Short, is one of the best I have owned-apart from cost to repair- it has been a good comfortable car. Lately it begun to sound kind of rough under and close to the rear of the car. One day it I smelled something like a metal grinding smell. Took it to the dealer and they diagnosed differential metal pieces from grinding...for $2000 they installed a used from a car lot rebuilt to be used with one year warranty.
Works great so far.
Driveshaft fell of at 60 mph. Riped the wiring, brake cable and caused the car not start afterwards
