The town's office of the Assessor should be informed of any unregistered vehicles. The assessor will investigate the claim by checking DMV documents and by interviewing the home-owners of the surrounding properties to establish a timeline as to how long the unregistered vehicle was/is parked at the residence in question. Complaints can be made anonymously.
