Very much agree - it also takes care of most time wasters.
BTW watch out for scams. I've heard of some fairly clever ones which involve a fake escrow agent. If you do escrow then use one of your choice. It's a tricky business because of the amount of expensive due diligence which a buyer needs to do - unless he's an engineer.
I would also digitise the logbooks. It doesn't take long to simply photograph the whole lot, and if somebody wants to see the maint records you can just mail him the whole CD full of jpegs. One should do this anyway in case of loss/theft because the plane can be rendered worthless by something like that.
