One option in lawsuits against dealers is instituting suit against the owners and/or employees. New Jersey laws held that the owners or the individual employees can be liable if they directly participated in the fraud or consumer fraud.
The New Jersey Consumer Fraud Act indicates that persons are liable, which includes fictitious persons – such as corporations – and real persons, such as individuals.
One resource is the Department of Treasury, State of New Jersey, wherein you can find out who the owners and the officers of the dealership are in order to assist your investigation.
