The security interest may also be perfected in this state after the expiration of the four month period; in that case perfection dates from the time of perfection in this state.(3) If the security interest was not perfected under the law of the jurisdiction where the vehicle was when the security interest attached, it may be perfected in this state; in that case, perfection dates from the time of perfection in this state.(d) A security interest noted on a certificate of title to a vehicle which is a mobile home or a manufactured home shall have priority over any other subsequent liens or security interests except for those set forth in subdivision (c) of section two thousand one hundred three of this article.(e) After a certificate of title has been issued in this state for a vehicle which is a mobile home or a manufactured home, and as long as the vehicle which is a mobile home or a manufactured home is subject to any security interest perfected pursuant to this section, the commissioner shall not revoke the certificate of title, and, in any event, the validity and priority of any security interest perfected pursuant to this section shall continue, notwithstanding the provision of any other law, including but not limited to section 9-303 and section 9-313 of the uniform commercial code.N.Y.
