Aircraft Stored On A Pad

Hello Folks,

I'm beginning to look into purchasing an aircraft and one (of many)
concerns I have is aircraft storage. In my area the only storage space
available is on a pad. Leaving a plane out in the Michigan (Detroit)
weather does not seem like the best idea. So, I have two questions...

Is there alternative storage I've not considered?

Can the airframe, engine and avionics survive in the elements, or am I
shortening the usable life of the aircraft?

Your comments and / or suggestions would be appreciated.

Thanks

GJ
