(iii) The vehicle represents exposure to extraordinary expense for repair or replacement under comprehensive or collision coverage.

(j) One or more incidents involving a threat, harassment, or physical assault by the insured or applicant for insurance on an insurer employee, agent, or agent employee while acting within the scope of his or her employment, if a report of the incident was filed with an appropriate law enforcement agency.
