Seems like the gullwing doors have the height issue to contend with, plus what are the chances you knock your 5-year old's chin on the way up?
I drive a sporty 2-door SUV and what I've long hoped to find was a 2-door suv with sliding doors - basically mini-van doors. The Peugot 1007 is the only vehicle I've ever seen like that and it was a little too econo-box for my taste.
