Mark,

Careful, I really doubt that that sissor lift will be able to lift your 911 without crushing something on the car. There are unreinforced body pans under there, there are A.C. hoses and oil lines under there, and I doubt that there are any reinforced places parallel to the lifts rails which you can use.

With a two-post lift, one can position the four arms where you need them, and up she goes without muss or fuss.

I would sincerely try to find one in your neighborhood or talk to someone who has one, and see if you can position your 911 over it before you even consider that kind of sissor lift.
