As far as a dealership releasing such information goes, sometimes a little common sense goes a long way. If they are in the business of selling USED cars, it's reasonable to consider that a potential buyer is going to want a good idea of what they're buying, especially given how much those dealerships are asking for used cars these days.
Providing prior owner contact info used to be common practice in such situations, but now that everyones' been convinced that they shouldn't even trust their neighbors, the country has gone off the paranoia deepend...all in the name of limited liability.
Good luck then if you decide to pull the trigger on the VX.
