I prefer to do suspension and gearbox work on a two post lift. Can it be done on a four post, yes but it is harder than on a two post. You end up ducking under the damned thing all day and you will hit your head.

Next to nothing it is pure luxury but when you have a two and a four post the four post gets used for general inspections and oil changes. Everything else happens on the two post.

People like a four post because it seems safer but I have seen cars almost roll off of the four post. You can dump a car off of anything but once you get used to it a two post is better for working, a four for storage.
