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.
