If you're about show, go for it.
If you have even the slightest care for the function of the vehicle, it's a complete waste of time. Risk of bending shit, shit popping open, shit breaking, shit leaking, shit generally getting fucked up. Added weight, added complexity, a shit-ton of money to get done right or a big ass headache if done wrong. Also, consider how important the door is for structural integrity during a crash... will the lambo hinge transfer force the way Toyota designed the door to react in a crash? Sounds dicey to me.
Sounds like alot of downside, when compared to the upside: gimmickey doors. In the end, that's all it is; a gimmick. Lamborgini did it because their cars were so wide you couldn't open the door in a regular parking stall... they were a practical addition to the lambo so that it could work as a daily driver. In any other case, it's just a for-show gimmick that has the potential do the opposite of what it did for lambo: make it horrible for a daily driver. Who needs a shower? Just go for a drive in the rain, lol. All the other wierd door hinge types discussed above are accomplishing the same feat - opening the door of a really wide car in a small space.
Sure, lambo doors are cool, but consider all the aspects before you jump into it. They sure do look pretty in the pictures around the internet... but would you really want them on your car to drive every day?
I'd rather have the 1000 dollars.
