Sorry for the necropost, but I feel this is important-
I was the one who bought this a few years ago from you. It was well worth the $500. The building was so great, it surpassed that of the lego group. I even modified it to add some medical beds in the front. To prove that I actually bought it, I might upload pics.
Anyways, I'm not even much of a Star-Wars fan. The reason I got this thing was because it just looks so darn awesome- it could really be a transport from any future universe. I'm probably going to use it in a comic soon.
I can build stuff like this, if not as good, myself. Check out my MOCpage-http://www.mocpages.com/home.php/27498 Some of my bests are my Scorpion tank V3, Troop transport tank, and Aliens Vig. Saber-Scorpion himself has 5/5ed some of my creations.
One question- why did you change the following from the time you took these pics to when you sold it to me-
The missile launchers, changed from white, blue, and grey to mainly blue and black.
The nose, changed from two grey pistols to two black pirate flintlocks.
Take away the printed domes on the wings for clear ones, as well as change the tips.
Make the bottom white instead of grey.
As well as numerous other things like the back pillars, the decorations on the sides of the top, the insides of the wing turrets, etc.
