I had a 2006 R350 4MATIC which was a nice highway car and had decent highway fuel mileage. The one thing I didn't like about the car was it was not easy to manuver in city traffic.

Ended up selling it as my Mercedes dealer service writer warned me that they were a money-pit as they got older. I am very close with my service writer who, I know, tends to look towards my best interests.
