6.9's "were" the money pits, but Mercedes up'd that title a notch with the pre
1995 S-class series. As a previous owner of a 1992 500SEL, I can tell you it
was a nightmare to repair & maintain, and mine was STILL under warranty. The
suspensions are troublesome, the a/c is troublesome, the power seats can be
troublesome and ANY dealer work is outrageously expensive, but still there are
few cars that are so heavy, yet drive, ride and handle so well.
