I made this model a couple of years ago and i only recently found these photos of it. My inspiration for building this model was because I was dissapointed with Lego's lackluster effort on the Sith Infiltrator.
Despite not having enough grey pieces to complete it i still think it came out alright. Although i don't have any photos of it there is a cockpit with a opening ramp at the back.
Currently I am working on making my own Millenium Falcon, which will likely take a while. If i am unable to complete it or can't make it I'm going to come back and make a bigger and better version of the Sith Infiltrator using some of the new SW peices i got with some of the newer sets.
--Sorry about the lack of photos, i could only find these ones--
