For second-hand purchases, a wide variety of vehicles can be found on a number of websites.  Local auctions are also a source of second-hand vehicles – mainly from state or utility fleets.  Purchasers of second-hand CNG vehicles must insure that the on-board CNG cylinders have been visually inspected.  These inspections are required once every three (3) years.  The inspections must be performed by a certified CNG cylinder inspector.
