Car stand

I bought my wife a new minivan yesterday and now she wants to park in the garage. So in order to make room and keep her happy, I want to put my FF above my buddies FF. So I need make a stand about 3ft high. I was thinking something along the lines of a high lift folding chassis stand, but without a bar connecting them on the bottom, similar to a saw horse?

Any thoughts or suggestions?
Thanks
Paul
