As someone who worked at the DeLorean Plant in Dunmurry Belfast N.Ireland John Z DeLorean may have a patent for Parts of the Gullwing doors now not all the door as such. When Mercedes and all the other great carmakers used Gullwingwinded doors they all had a problem with making them water tight and no one was able to overcome this and the rain leaked in all over the place.This is the reason why Gullwinged were not popular with the car makers. When the great man John Z was confronted with this problem he got to work before the DeLorean went into production and invented a new type of rubber seal. So its not the Gullwing doors that are his patent its the actual rubber seal.Look at the seals on the doors they are a wonderful piece of engineering Joe Murray Clock Number @ DeLorean 1065 [Non-text portions of this message have been removed]
