California Code, Civil Code - CIV § 1795.5

(a) It shall be the obligation of the distributor or retail seller making express warranties with respect to used consumer goods (and not the original manufacturer, distributor, or retail seller making express warranties with respect to such goods when new) to maintain sufficient service and repair facilities within this state to carry out the terms of such express warranties.

(b) The provisions of Section 1793.5 shall not apply to the sale of used consumer goods sold in this state.

(c) The duration of the implied warranty of merchantability and where present the implied warranty of fitness with respect to used consumer goods sold in this state, where the sale is accompanied by an express warranty, shall be coextensive in duration with an express warranty which accompanies the consumer goods, provided the duration of the express warranty is reasonable, but in no event shall such implied warranties have a duration of less than 30 days nor more than three months following the sale of used consumer goods to a retail buyer. Where no duration for an express warranty is stated with respect to such goods, or parts thereof, the duration of the implied warranties shall be the maximum period prescribed above.

(d) The obligation of the distributor or retail seller who makes express warranties with respect to used goods that are sold in this state, shall extend to the sale of all such used goods, regardless of when such goods may have been manufactured.
