We're very happy with our BendPak 4-post lift. We got just the standard one, but special ordered it powder-coated black instead of BendPak Blue. We liked it so much that we ordered and installed a BendPak 2-post lift, again Black. Unfortunately, the bay with the 2-post in it was about 2" too short for the full size one with the overhead cables. We could have put it one bay over, but then it would have been a long way from the tool cabinets. We're doing just fine with the short one with the cables that run across the floor with a hump.
I would think that with the 4-post, you'll have to park the Slingshot on the bottom, unless they have a solid floor these days.
