How to list a certified car by private owner
List it here but unless you are selling it with a guarantee I would not sell it as "certified" ----- http://www.cargurus.com/Cars/sell-car/
Pretty sure a private owner can't sell a car as certified pre-owned unless it comes with a detailed written warranty. If it was purchased by you as a "certified" it likely is no longer certified, but the warranty might pass to the next owner. You would need to check with Honda for that info.
