The seller may have given oral assurances of reliability while the written contract disclaims any implied warranties and contains a merger clause purporting to negate express warranties. You must decide whether the parties actually intended the writing to be the complete and exclusive statement of the terms, which would entail ignoring the oral statements. [See Com C §2202.] You may consider the parties' situations and relative sophistication when determining their intent on the issue of whether the written agreement is integrated within the meaning of the parole evidence rule. [See Haggard v Kimberly Quality Care, Inc. (1995) 39 CA4th 508, 518 (construing CCP §1856); Sierra Diesel Injection Serv., Inc. v Burroughs (9th Cir Nev 1989) 890 F2d 108, 112.] Also be mindful of the possible application of the Consumers Legal Remedies Act. [See CC §1770(a)(14); Wang v Massey Chevrolet (2002) 97 CA4th 856, 869–870.]
