N.J. Stat. § 56:8-70
The written warranty shall require the dealer, upon failure or malfunction of a covered item during the term of the warranty, to correct the malfunction or defect, provided the used motor vehicle is delivered to the dealer, at his regular place of business, and subject to a deductible amount of $50 to be paid by the consumer for each repair of a covered item. This written warranty shall exclude repairs covered by any manufacturer's warranty, or recall program, as well as repairs of a covered item required because of collision, abuse, or the consumer's failure to properly maintain such used motor vehicle in accordance with the manufacturer's recommended maintenance schedule, or from damage of a covered item caused as a result of any commercial use of the used motor vehicle, or operation of such vehicle without proper lubrication or coolant, or as a result of any misuse, negligence or alteration of such vehicle by someone other than the dealer.
