I live in southern part of Finland, near coast so there tends to be less snow here than up north. Some years are better than others, but recently it seems to be steadily degrading. Must be the global warmingPetros wrote: Kumppari, I would think Finland gets more snow than that. How cold is there in a typical winter? Do you have to do anything special to protect the car when you park it outside in those low winter temps?

Snow recrod in finland is 190cm from year 1997 and temerature record -51,5c from year 1999. Normal temps would be somewhere beteen -5 to -20c and snow anywhere up to about 50cm. Really changes a lot between locations and years.
Oddly enough, there seems to be no special things to be done in normal everyday (night?) parking situations, other than plugging the heater cord into socket and possibly putting a car cover on. They usually work qiute normally even in colder times. I have even seen soft top cars being used during winter (tops up, ofcourse).
There is, hoever, many things to do as a preventive measure before winter. Check your battery, since they work less effectively in cold. Dead battery seems to be one of the more common problems. Keep jump cables with you, or get one of those nifty litte porable power stations that have integrated working light and compressor in them. I have put 12volt cigarette lighter socket in my boot just to keep one charged all the time. Some people use thinner oil during winter, this helps during cranking. Other fluids should also be checked like coolant, washer, power steering, aircon. If in doubt, change brake fluid. There could be water in the pipes. Handbrakes freezes, so levae it in gear instead. I dont know yet if this is a problem in tercels. Get some rubber floor mats, these are good in keeping water from soaking in the textile carpets, and are easy to empty. Trying to keep the insides dry will help defogging windows. Using aircon will help also. Doors can freeze shut, use silicon on gaskets. Some say brake fluid works too, but it may damage paint.
There is pobaly more things that I am forgetting, but pretty much basic maintenance and care is all it takes.
