When a charitable not-for-profit organization that is exempt from federal income taxation under Section 501(c)(3) of the Internal Revenue Code becomes the recipient of a motor vehicle by means of a donation from an individual, the organization need not send the certificate of title to the Secretary of State. Upon transferring the motor vehicle, the organization shall promptly and within 20 days execute the reassignment to reflect the transfer from the organization to the purchaser. The organization is specifically authorized to complete and execute the space reserved in the certificate of title for a dealer reassignment, notwithstanding that the organization is not a licensed dealer. Nothing in this Section shall be construed to require the organization to become a licensed vehicle dealer.
