i am sure their are different grades of lifts.
at the new car dealership i work at. they only buy Bendpak lifts.
when we had our old dealership they had about 50 lifts. most were about 25 years old.


when they remodeled the import store they replaced every lift with new Bendpak lifts. i do believe there are about 40 lifts in the shop. i think most all are 2 post asymmetrical. i think the alignment one is a scissors type lift. when lowered is sits completely flat to the floor in the pit it's mounted in.
at the bodyshop / service center there are 7 2 post asymmetrical and 1 scissors alignment in a pit. as far as i know they have had to do 0 repairs on those lifts in the 5 years we have been at our current location.
the alignment one is pretty cool. the front is open in the center and there is a line of lights built into the lift on the inside of the ramps for easy underside viewing.
