 I had this car for less than one year, enough time for me to have all sorts of service issues.  I was sold this car as a "certified" vehicle which is marketing bs talk for "used" car.  In a nutshell, I had problems with the retension belt.  I drove 8,000 until the belt had to be replaced. I argued that this is something that needed to be covered under warranty and even the Benz service guy agreed. It wasn't so I had to shell out $440.  I bought a Hyundai Vera Cruz at about the same time as the C280. I'm on the verge of exchanging the C280 with a Sonata.  Ata least my expectations won't be high with a Sonata.
