It is an unfair practice for a manufacturer or distributor to prevent or require, or attempt to prevent or require, by contract or otherwise, a dealer or an officer, a partner, or a stockholder of a dealer to sell or transfer a part of the interest of the officer, partner, or stockholder to any other person. A dealer, an officer, a partner, or a stockholder may not sell, transfer, or assign the franchise or a right under the franchise without the consent of the manufacturer or distributor. This consent may not be withheld unreasonably.
