It's an interesting photo. If it were not a convertible, Shaq would not be smiling.
If you're old enough to remember, VW made an ad with Wilt Chamberlain, about the same height as Shaq but much more fit, trying to get into an old Beetle. He couldn't do it.
I'm 6'1" and I actually move the driver's seat forward from the rearmost position because the arm reach is uncomfortable.
My friend Andy, who's 6'6", fits okay in the passenger seat, but would be hard pressed to sit for long in the driver's seat.
