I have a Bend Pak 9000 pound four post lift and getting it adjusted correctly was a problem. The lift releasing design requires an air source. I used a small portable air compressor rather than Bend Pak's self charging air kit. In my opinion I would rather have a manual lever releasing system to lower the lift. My old two post lift has two manual release levers and the stops are on the outside of the post where you can see them. That design seems better and safer, but if you are just storing a vehicle, then the air release system might not be a huge problem. Bend Pak does offer a lot of accessories for their lifts, which if you want to spend the money you can get the benefit of a two post lift with a four post lift.
