Cal. PCC § 10326

In establishing bid specifications for the acquisition of motor vehicles and in determining the lowest responsible bidder, consideration may be given by the state to the probable resale value of the vehicles as determined by recognized published used car marketing guides and other established historical evidence of future used motor vehicle value or, in lieu thereof, by contractual guarantee of the apparent low bidder that the resale value of the vehicle will be no less in proportion to bid price than any other comparable vehicle complying with specifications for which a bid was received.
