I transport a manual wheelchair in my cube nicely. My BF is confined to a chair. He uses his power chair around the house but we take the manual chair with us. Unfortunately, I am not much help on the mod lift department, but I can tell you a foldable manual fits perfect in the back. I stand it straight up and just strap it in with a bungee cord. The handles tuck in behind the headrest so i never even see it in the rearview mirror. It is so much easier for me to lift the chair in and out of the Cube than it was getting it out of the Mazda for sure!
