Lambo door conversions

Why do people insist on doing this to Hummers, Porsches and other vehicles?

First off, to the idea was always lame. It appears diffcult to get in and out of a Lambo, I've been in one, once. When you open the doors you have to be careful to not hit the garage door track, the garage door itself, etc. Add to the issue the parts to hold the door up are a wear item other vehicles do not possess.

How well could doors that were designed to rotate horizontally fit when modded to move vertically?

How often are your doors open for people to see this modification? I suspect in a 24 hour day my car doors are in the open position less than 2 minutes, who am I impressing if I get this modification?

I see many cars with Lambo door mods in the DuPont Registry, to me this is a deal killer not deal maker, your opinion?
