At that age a car's condition is the telling indicator. The quality
problems arose with the cars' complexity, especially the electronics.
This body was powered by gas and diesel engines. The gas motors were a
straight six, a 4.2L V-8 and a 5.6L V-8. The diesel was a 3.0L straight six.
This model was sold in Europe as a Limousine and has some of those
attributes, especially the 560SEL. The cars were not designed for fuel
economy or low maintenance cost as are American models. So if you don't
drive much or the fuel cost and maintenance isn't an issue or you do
your own the maintenance then buy one. If you do, have the timing chain
checked for wear and stretch for if it breaks the repair cost will be as
much as this car's purchase price.
