4 post lift vs. 2 post lift. Pros and Cons.

Work on my own stuff mainly. Hopefully help some others out that could use it occasionally. It would make things easier for me. My back and other parts are wearing down like a lot of us old farts and I want to extend the time I have to keep working on cars. I don't have to do anything for a living any more. Sooo..... I just wanna have some fun. Lol

Ok, more for work. That's a 2 post. 4 post is more about storage. That would make my decision "RIGHT THERE".
