I just want to add that having owned two VX's so far, I've only come across the window binding problem on one and had no other issues. Both I've had have been used, and they've been great. No oil consumption issues, and my gas mileage has always been about 18-19 mpg. My current VX has 63,400 and it runs like a top.
Good luck in finding one you want. I say go for it!
