My 6'7" uncle is as much a Subi nut as I am. (well, MORE of a Subi nut, truth be told) I don't know how on earth he manages to fit in the Subis, but he does it somehow.
My hubby is all leg. He doesn't need extraordinary headroom, just lots of room for those giraffe legs to fold up. He also has flexibility and circulation issues, so if he drives, he needs room to move around a bit. That didn't exist for him in the Subarus.

The looks he used to get as he folded into the Beetle!
