Im looking for another car and Im thinking about a used Mercedes-Benz E 350. Im concerned with the E 350's reliability and cost of maintenance, repairs, etc. I know they had problems in the early years when it 1st came out in 2003 but I believe they should have been fixed by the year 2006. 2009 was the last year the W211 was manufactured. Im looking for a Black on Black E350 with less than 50k miles. Im not sure about purchasing an certified pre owned or an extended warranty. Does anyone know if you can do your own repairs on the W211 E350 and what kind? I know the dealer would have to do the brakes because of SBC. Do you recommend buying from a dealer or private party that has all service records? I would appreciate any input from anyone that had experience with this car. Thanks in advance for your time and help.
