 We purchased a certified MB from a Benz dealer in NY. The car had 40k after 2 months engine ticking when starting. Bring it in oh we can't hear it. OK 6 months later now it's louder. Bring it in, leave it 2 weeks ok we hear it and it's a known Tech bulletin. Service advisor says 2 months we need to order a new motor from the assembly line. Then calls back and says your VIN # does not fall into this category so we will rebuild yours here. Replaced all main engine bearings. A month later pick it up no more noise but now it has a vibration at 4200 rpm. Dealer says can find it. A year and a half go by now 70k. The trim on the driver's door falls off, license plate light goes out, its a hid bulb and 3hrs labor. Battery goes dead, you can only get this battery at MB it's 300$. The last straw for us was the airbag recall. We get the notice, I call MB they say we don't know when where getting the bags just be patient. OK ,a month later it hits the news and we get a call from MB saying don't drive or drive at your own risk. I was happy to tell them we sold it. Funny thing they never even asked who purchased it. Not bitter just wanted to pass our experience along, make your own decisions. I own 5 cars at the moment and had always wanted a Benz. So that's why it's the 2 happiest days of my life, the day you get it and the day you sell it.
