Dhollin,
Glad you joined. As far as oil changes, if you don't want to do it yourself, then find someone local that works on Mersedes or BMWs. It's not hard but they have to do it correctly. Get the oil filters that are made in Germany ( Mann brand) and use the Mobil 1 0W40 grade. In a pinch you could maybe use 5W40 Mobil 1, but that's your choice. Do a search for oil changes, Mobil1, or oil filters and all this should come up.
Great little cars, never thought I would love it so much. I put in a Black mesh grille, some new emblems, some wheel graphics, have some lighted door sills on order. Also bought some bigger brakes for the front (SRT6) with calipers, I'm going to overhaul the calipers, flush the system,etc.
