H3,
I would highly suggest you extend your search to find a VX that has not spent it's life in New England...
I grew up in Chelmsford, Ma (not too far from you) and therefore, my autobody career started back there. So, I have worked on my share of rusted vehicles...
Not only do you get the rust spots on the body, but what I really hated, was quite often, the small 10mil bolts would get rusted and when you tried to take them out they would snap right off. Then your drilling and extracting, sometimes tapping new threads, etc...
Moving out to Az and working on vehicles that haven't been cursed with the rust "cancer" made a huge difference in how I viewed used vehicles... and our beloved VX's definately fall into that used category.
Good luck in your search!
Dan
