Mine is facing its first winter with me at least, as an outside car. I always tend to think that a car that is used - ie in the airflow, will fair better than one which is rarely used. I have already replaced my rear lights - easy to do and it has had one of the bolt holes sealed by me in the process. There are no signs of leakage in my 7 months of ownership even when the local guys have cleaned it with a pressure wash - not something I generally would allow to happen. I also replaced the rubber strips that seal the boot shutline - this is cheap to do, and may have helped.
