VIN search disclaimer This Chevelle website is not designed to help you locate a car you owned 20-30 years ago. To my knowledge there is no known database of a car's VIN and its past/current owner. Such a public database would be a gross invasion of privacy. Law enforment agencies can run a VIN in most cases to find the current owner but can only do so legally as part of any police action such as a suspected stolen car or one that has been in an accident to verify the owner. They CANNOT, legally, do a VIN search for personal reasons such as a favor to a friend.
