My VX has almost 90k on it now.
Like you, I have (for a long time) longed for a larger vehicle, something 4-door, that can haul more crap and people easily, and is 4x4. Sure, the VX isn't the most practical SUV you can own, however, it is the coolest SUV ever.
In my case, I have decided I am going to buy another SUV (most likely a 1988-1991 Trooper) and keep my baby VX, clean her up and drive her much less, while I beat the hell outta the Trooper on a daily basis. I have been watching the used Trooper market for over 2 months now, and I am 100% positive a quality used Trooper can be had for under $2000.
That is the route I will go.
So, unless you have other circumstances preventing it (money/space/time) I say keep your VX and buy a decent used vehicle to fulfill the needs the VX lacks.
