I've moved to Oulu just one week ago and took my car with me from Italy. Temperatures here are between 0° and -12° at the moment (but it can get easily to -20° for what I've heard). I have no experience whatsoever in taking care of a vehicle in such cold conditions and I have a few questions:
- The car is parked outside at the moment: starting from the basics, for how long should I wait for the engine to warm up (that is, after turning it on) before driving?
- General question: what are the risks of leaving the car in the open during the whole winter? For example, battery, electric system, plastic/rubber parts, paint, etc... What if I don't use it for several days in a row?
- I'm looking for a permanent accommodation: is it crucial to choose a flat with a warm parking spot?
- I see that the majority of cars parked outside are plugged through a cable to some electric plug, which I assume is to supply some engine block heater. Do cars here come out of the factory with engine block heaters or are they installed afterwards?
Note that my car is just one year old and in perfect conditions.
Any other comment/suggestion is "warmly" welcome

Thank you in advance for your time, cheers!
