Tom,
When the database is built, I think we've decided to share some information that doesn't put anyone at risk (number of certain color - options etc) however I don't think that we'll ever expose all of the information like addresses, VIN numbers etc.
Once everything is pulled together, we might offer VIN searches etc if everyone agrees to it.
This is a work in progress that requires some software I don't have yet and a lot of time to enter in almost 20 years of registry paperwork.
Anyone here a MySQL / PHP guru and have a couple of weeks to donate? ;D
Chris
