I think it's important that this CRG database exists and those have created it by either their own investigations or submissions from others that it be kept confidential. If people wanted their vehicle information known to others they would go and submit their details to one of the on line registries and get a certificate for it. For some high pedigree vehicles its all the rage to say that "my car is in the registry". To each his own.
With that being said, I also think it is important that if someone asks if a particular vehicle is already within the CRG database that a response be provided yes or no. However that does not imply that the information will be released. There is always the PM route of communication if any information can be divulged and needs to remain out of the public eye, but yet again that is to discretion of those that created and maintain this database. I am also sure that CRG members here as well as others on this site would like to help any potential buyer of a vehicle as much as they can but you need to be able to ask the right questions. In the end it your own choice armed with what information you have obtained yourself along with any answers to the questions that you may have received from this site. I think like my drivers licence it's a privilege to be here, not a right.
Danny, I wish you well and God Bless you, don't let these posts whatever direction they may have taken distract you from what is important in life, your family!
