I prefer the Unlimited (which is synonymous with 4 doors), just for that little bit of extra space, and from pictures with back seats down, it appears that there's a bump in 2 door Wranglers whereas the four door Wrangler seats lie flat which is nicer to spread the swag on...
Have seen a couple of nice 2 door ones on carsales though and am not closing my mind completely on those... my research continues.
Thanks again for the feedback, it's really appreciated, especially because I know that there's nothing I can give back here... my knowledge on cars is pretty much non existent when it comes to technical questions. I can only hope some other readers benefit from the contents in this thread also - am sure I'm not the only WranglerVirgin on here
