Something else to think about, not related to the engine.

Most of my Benzes have had a flaw, a weakness, that will irritate you if not careful. The plastics they use , at least in the cars I have owned, don't like sub Zero. You can cut your interior, door panel, seat covers any vinyls, with something as simple as the metal clip on your seat belt.
Be careful letting that seatbelt just retract itself. And be careful with the vinyl parts when they are really cold.

The "bruises" will show up as cuts when the weather improves.

I don't know why this is. Just something I found out about the hard way. Something about what they are allowed to put in the plastic, when it is made in Europe, I guess.
