¶17 Section 27 of the Restatement (Second) of Contracts provides that:
Manifestations of assent that are in themselves sufficient to conclude a contract will not be prevented from so operating by the fact that the parties also manifest an intention to prepare and adopt a written memorial thereof; but the circumstances may show that the agreements are preliminary negotiations.
Restatement (Second) of Contracts § 27 (1981). In support of the proposition that Arizona has adopted this section, the court refers to three recent decisions of the court of appeals. See Tabler v. Indus. Comm'n, 202 Ariz. 518, 521 ¶10, 47 P.3d 1156, 1159 (App. 2002); Johnson Int'l, Inc. v. City of Phoenix, 192 Ariz. 466, 470-71 ¶26, 967 P.2d 607, 611-12 (App. 1998); AROK Constr. Co. v. Indian Constr. Servs., 174 Ariz. 291, 297, 848 P.2d 870, 876 (App. 1993).

¶19 Ry-Tan also argues that the Arizona School District Procurement Code (the Code), Ariz. Admin. Code (A.A.C.) R7-2-1001 to R7-2-1195, dramatically altered the landscape of school procurement contracts and effectively displaced the common law rule of Covington. The state board of education adopted the Code in 1987 pursuant to legislative authority. A.R.S. § 15-213.J (Supp. 2004). By its terms, the Code governs the "expenditure of public monies" for a school district's procurement of "construction, materials and services." A.A.C. R7-2-1002.A.
¶20 The legislature, of course, can modify or abrogate the common law. To do so, however, it must express its intent clearly and, "absent a clear manifestation of legislative intent to abrogate the common law, we interpret statutes with every intendment in favor of consistency with the common law." Pleak v. Entrada Prop. Owners' Ass'n, 207 Ariz. 418, 422 ¶12, 87 P.3d 831, 835 (2004) (citation omitted).
