As others have already mentioned, just park it.
Here's the best way from what I've heard (and done myself)
When storing:
-Wash the car first, and park it uncovered (or covered with a bed sheet). Do NOT use a tarp as it will hold in moisture
-Disconnect the battery and keep it from freezing (take it in the house, etc.)
-Stick a rag in the exhaust to prevent bugs/critters from entering
-Make sure all the windows are shut tightly
-Overinflate the tires a little bit
-Tape a note to the steering wheel saying DO NOT DRIVE and a few reminders of what to do before running the car (install battery, pull out rag, etc, etc.) You WILL forget by spring!
Don't start or drive the car over the winter. That 10 minutes of running it will screw it up.. remember to consider the oil & fluids as "bad" after about a month.. so you don't want to start it with bad oil.
When spring comes:
-Reinstall battery
-Necessary: change the oil & filter
-Optional: trans fluid & filter, brake fluid flush, coolant. Why start a new year with old fluids?? Just change them now and you're good for 2 years!
-Pull rag out of exhaust
-Disconnect ignition wire (or pull fuse) and crank for 10 seconds to get oil through engine. Reconnect wire/fuse and start car. Let it warm up properly, then check ALL fluid levels before driving. Check tire pressures and ENJOY!
If you end up not having a place to store the car and want to sell, I'm right nearby in Oakville
I don't have a place to store it either, but can't resist buying a 3rd MB
