Your gas guzzler engine technically is a heater as about 70% of the fuel is converted to heat and only the reminder into HP.
My older diesel takes over a mile to get warm starting at 50F. Newer engines are more efficient, meaning more HP and less heat. The cdi I drove took about 3 miles to warm up from 50F and what European members report -those in colder countries are coming with aux heaters not only for comfort heating, but to bring the engine to proper temperatures as in city driving in cold weather those engines would never come to recommended temperatures.
So enjoy the heat

The cold never bothered me. In the cold, all I needed to do was to put on more warm clothes, scarf, beanie, and gloves. The summer heat has always been the trouble; even after I took off all my clothes, it's still hot. I fear when global warming reaches its peak, I'm dead.

Dont worry. Your mercedes will keep your warm Lots of michigan winters in several different MB's. Seat heaters are nice if your car comes with them.

There are parts like the thermostat (certain Euro CDIs have two of them and even MB workshops often neglect the other one) and the electric circulation pump tend to fail at some point and need to be looked after. If everything is working, even a 200 CDI engine will keep the cabin warm.

I experienced that smaller engines get warmer as they have to work harder even on idle.
A month ago I slept in my truck with 7.3 l diesel engine at -25 F (-29C) idling. Even the truck was well warmed at the evening, through the night the engine temperature dropped to the bottom of the dashboard scale and the cabin heat was minimal.

True for the engine itself but if you use a lot of engine heat to warm up the cabin, a small CDI is too efficient and does not produce enough heat. But this is more of an issue at extreme temperatures. Modern MB diesels also have an additional electric heater that provides heated (not hot but warm) air almost immediately.
