gullwing and lambo are not the same. some of the new half-mil benzes and the old deloreans had gullwings, where the top of the door is mounted to and hinges off of the roof. on lamborghini doors the door is mounted and hinged on the front fender and suicide doors is on the rear fender. the conversion was done on a crx and the guy said it was 10 grand. so basically, not even close to worth it.
