| This is your first post and it is one of those? Pretty lame.
I'll tell you what I tell everyone for a question such as this: 2D vs. 4D is strictly a personal preference and a reflection of what you use your car for. I use my car more as an actual car than a BMW. I prefer to give my passengers the luxury of their own door, and that's just how I feel.
Basically, examine your requirements and see if a 2D or 4D fits your needs better.
