Bring your California Certificate of Title, or your lender's payoff details if you still owe on the car. Also bring your current registration, a valid photo ID for every owner listed on the title, and every key and remote you have. Service records, the owner's manual, and any accessories that came with the vehicle complete the set. With these in hand, the appraisal can reflect your car accurately and the paperwork won't slow down your move into your next Chevrolet.
