My 2 cents:

Everything Etl said is true. But like he said, if you give your VX a little regular TLC, most of the issues he speaks of can be avoided. My windows used to stick, but I lube them up with silicone spray at least once a month and they are still rolling strong and fast. I do not have a lift (yet), and my CVs are fine, and I live in an extremely dry climate. My VX does burn oil, but I dilligently watch it, and refill as necissary.

I think the most important thing you can do, if you decide to buy a VX, is be patient, and look nationwide for the best one you can find (low mileage, no previous mods, etc).
