 New car stalled 4 times. After pulling over and waiting for a few minutes car would start up again. Took it every time to a dealer. No problem found.I hear grinding sound, Dealer says normal. never heard that in any of my 20 other cars I have bought before. Soon as warranty expired, there was a problem. During test Dealer claimed that the Compression cable broke. Cost $2000+. I still hear noise and (sometimes) gears shift at a very high RPM.Went to get Smog test. They said they could not get steady RPM of 2800 to perform the test.This week the door handle broke. Cost $500.I would say that MBZ has VERY POOR QUALITY.Buying MBZ 1984-2007. NEVER AGAIN.
