If you notice the windows don't work as well as you like, or the headlight gasket is peeling off or missing, you can certainly use those as negotiating points - it's unlikely that the dealer knows they are common problems. Another one on the 1999 models is peeling chrome rims. I'd also carefully look over the intake manifold gasket as that is another common point of failure for some reason. Has the VX been lifted? Even if it hasn't, look at the CV boots for tears or signs of leakage. While they *are* owner-servicable for about $20 each in many cases, to the dealer that's a $700+ repair - another good point for negotiating.
By giving yourself only 3 hours to make a decision, you've really taken away much of your edge when it comes to negotiating - especially if the dealer knows that or can sense your urgency. Your smartest move, unless the dealer really offers you a great deal, is to take your chances and come back in three weeks. There's a good chance he won't have sold it, and at that point will really be willing to negotiate. And as others have pointed out, there are a lot of VX's out there for sale, so it's really a buyer's market.
You should also consider that the Ebony is a common color, and that the 2000 has an upgraded climate control system, comes in the Grey/Black interior, and has the 18" rims. If any of those things interest you, I would hold out for the 2000 or 2001. And if you really want the red/black interior and can only find a 2000 or 2001 with grey/black, I'd be interested in doing a swap with you.
I hope the input helps. Good luck!
