 used 2007 R350.Did my homework but went against my gut and intelligence and bought a clean used r350 with 51k on it.Had the MB dealer check it out, check the codes..& 200plus to be extra careful. the history was good, so I bought the giant car my wife liked.I even forked out $400 to have the trans serviced to be extra thoughtful.Every two weeks since it goes to the dealer. One expensive thing after another.Power steering unit $1,100.00Gas vapor purge valve $500.00 plus.Peeling rubber coating on controls...Now HVAC control stuck on full heat...Conclusion.It is not about the model, it is about MB's now third world manufacturing and reliability!ForSale
