IMO gullwing doors would be a pain in the rear end if you are parked next to some one... not a alot of room to let the door swing up, its hard enough to try to squeez inbetween the door when you have it cracked. I normaly park away from people in the parking lot but it never fails when i come out of the store someone has ended up parking right next to me... pisses me off.

 

they suck to do, you have to relocate almost every part in the door to the front and hen make brakets and latches to the front, then move hinges to rear... its a pain

 

BTW dont most ions have suicide doors? lol
