Its hard to say about leak indeed, without more info/photos.
Personally, if you are serious about owning a VX, I would be patient, and keep looking. Test drive 2 or 3 so you can get the feel for the vehicle, and if you are really smart, be willing to travel for the right one. I got lucky, but I know many folks on here have bought VXes from states away, sometimes from across the country. It is well worth the extra effort and time to find the right one, imo.
The first step to your success is already done, that is, signing up with this forum!
A few points of advice:
1) Try to find one with the factory roof rack- they are VERY hard to get now
2) Try to find a 2001
3) Check the oil on every vehicle you drive, some VXes have an oil burning issue
4) Don't be afraid to ask us for help, find a local VX owner on here, meet up, talk tech and go for a ride!
Good luck,
Bart
