This year and model has wiring harness issues. Make sure the harness has
been replaced It was a factory recall item. W140s also have known problems
with the AC evaporator unit. These have a high rate of failure. It is a 23
hour job to remove and replace the dash the get to the evaporator....plus
the cost of the evaporator unit. Somewhere in the $2500 to $3000 range for
the fix. The drive trains on these cars are solid....it is all the
electronics and extras that cause the problems. Always buy a warranty if
one is available....you will need it.
