What To Do With A 99% Completed Army?

I started and shelved this mint colored Necron ages ago. It has sat in a partially completed state a foot away from me for so long it developed a thick coat of dust. In a spurt of spring cleaning I decided to get the army out and sell it.  After looking at it, I decided it needed to at least be based, and have all of the existing units finished. This was fun. It wasn't supposed to be. It was supposed to be a chore that would lead to me being able to get rid of the army easily. What should I do with this force? I know it is not up to my current standards, but I'm kind of fond of looking at it. (probably why I went into Sons of Horus in the first place!) If I decide to sell it, do I need to paint up the remaining kits to round out the force? Do I sell this separately, or as one listing with both painted and NIB kits?

Desert Malcador With Battle Cannon

I needed something to kickstart my painting again, so rather than paint this tank for one of my forces, I decided to paint it as a stand alone piece. As far as tanks go, this one has seen better days. It is painted as a beat up desert vehicle with oil leaking everywhere. I was tempted to add sharp irregular pale blue camo to this, but resisted. In hind sight, the blue would have worked really well. I haven't quite regained my painting mojo, but this was fun.
