I would tend to agree with Doug although I have had no problems with mine since purchased last December with 69K miles. As an aside, I love working on my VX and take time every week to check for leaks and listen for any odd noise. I have time to regularly keep her lubed, washed, and in top shape.
It had already had the window fix done and was in great shape with all maintenance up to date.
If you purchase one in good shape the mechanical side may not be an issue, but for me the gas mileage for a college student, and the fact that it's hardly 4 people friendly due to the difficulty getting into the back, is the real concern.
If you decide to purchase you can probably post a request for a member here to look it over before you make a trip. I know you'll find the family here more than willing to help where needed.
Good luck with the search.
