Before buying my 2 post, 9000 lb. rated lift 2 years ago, I did some research. I compared the 2 post against the 4 post. Each design is fine in its own right, depends what you want to use it for. I liked the 4 post because you didn't have to bend down to align the lifting arms and it could come with casters to make if mobile. Move it where you want it. There was also an optional center sliding jack that would allow you to lift the car for maybe brake work. I think the 4 post to me is better suited for storage. It certainly doesn't preclude you from working on your car. I originally wanted a 4 post, but they also take more room length wise because of the drive up ramps. I would have been cramped with the 4 post. Overall, I'm happy with my 2 post. As previously mentioned in another thread, its not user friendly with an x frame car. What I do with my '62 is, I drive it in the garage, jack it up, dollies under the wheels and then move it in place. Not a lot of distance to spare, especially in the front. Raise it and put a tall jack stand in the front and rear; I don't trust anyone's lift including my own. The stands give me peace if mind while working under it. I then work on the car. I know it sounds like a pain, because it is, but that's what I do. I like the 2 post because everything is hanging right there in front of you. No obstructions. I don't think a 2 post is good for long term storage, like over the winter. I wouldn't leave anything on a 2 post any real length of time. It all comes down to what you are going to use it for. They both have their assets and liabilities. I might also add that this Spring, I'm thinking about having the roof raised on my older garage part and buying a 4 post lift primarily with storage un mind. My lift is an Eagle brand, Carmine.
