wow what I wouldn't give to have a lift like that in my garage..

I think that defeats the purpose of ramps. From pics I've seen the ramp part(the angled section) of the ramp is detachable.

The back tires are on "cribs" in the last picture. Yes, you have have to jack up the car and slide the cribs under. I have the ramp ups too which are pictured under the rear tires in picture 3 and 4. The cribs are not necessary unless you want the whole car up in the air like that.
