Really depends totally on what you want from the car and if you plan to mod it a little or alot.
If you want an exclusive car and are concerned about resale values etc, get the 2 door and dont mod it.
If you plan to mod, then performance is an issue for you. Do you just want to go fast in a straightline or on the street? Or does tracking the car interest you?
For street crusing and dishing the occasional chop then go the 2 door, if your thinking you will be hitting the track a bit I'd go a GDB.
Finally, if its about an all round car that you probably wont mod much, then go the GDB or a camary.
