Here is a part of my Dark Angel army - 3 Land Raiders.
I did one with the front door opening (it closes as well!). It was a real pain to do, particularity getting the painting done having to do the inside part way through building, but I regret doing the others glued shut once it was finished. I have stuck various bits of Dark Angel paraphernalia on the vehicles - gives them a nice feel. One of my marine squads is disgorging from the front Land Raider. To note I hand painted the Dark Angel insignia I was having too much trouble with getting the decals to stick flat and to say on.
