2 post vs 4 post for long term storage

Hi all,

I am thinking of getting a lift to store my 67 convertible dart.

A 2 post would be the most useful but I suspect storing a convertible (or any other car for that matter) on a 2 post with all the cars weight on 4 points might not be good for the long run.

4 post makes the most sense for ease of use and storage and offers MOST the same usefulness.

What say you?
I have a 2 post. However, for storage of any kind or if you want to put another vehicle under it, highly recommend a 4 post. My next lift will be a 4 post just for this reason
