California Code, Insurance Code - INS § 671

No insurer issuing an automobile collision policy, as defined in Section 660, or a policy for comprehensive coverage for an automobile, as defined in Section 11580.07, shall refuse to issue the policy of insurance, or the policy in combination with other coverages, when the refusal is based solely on the age of the automobile to be insured, if the market value of the automobile exceeds two thousand five hundred dollars ($2,500).

This section does not apply to any policy which includes coverage for losses resulting from wear and tear or from normal deterioration of an automobile or its component parts, nor to any policy which provides coverage for an antique or classic automobile.
