Hey designerguy,
It's all about getting the service history first of all(if youcan) and second of all it's all about the special TLC you are going to give your VX. Instantly change over to synthetic oil products for everything. Like any 4x4 you have to keep to a good maintanance schedule. Do that and there should be no major problems.
Yea, you'll get your minor stuff like leaking headlight seals, windows that don't want to work and/or mystery code pop-ups but all these can be fixed easily with the help of the great people on this web site. There is enough knowledge here to sink the Bismark.
Good luck with the new ride..keep us posted.
John
