From a maintenance stand point, it is a pretty solid car (all the Mercedes in it). Regular oil changes with Mobil 0W/40 with a new filter are the top priority. In reality, you can do these yourself and save a lot over what the dealerships charge. There are several systems that allow you to suck the oil out of the car through the dipstick without getting underneath it. The filter is easy to get. The oil is easy to find. Good luck with your decision!
