I've always wondered why there is not a system available to the Trade where we can check all offered cars (potential p/x or otherwise) against the PNC? I understand HPI and Experian sort of cover this, but if the Police/Border Control/Interpol were on the lookout for specific non-stolen vehicles(eg a car suspected of being involved in an accident, child abduction, trafficking etc), we could check what comes in on a daily basis against the 'wanted' list. I can't see a down side or am I being too simplistic?
