If the car continues to be used after it is fully depreciated, there will be no further depreciation entries.
If you sell the car after it is fully depreciated, you 1) debit Cash for the amount received, 2) debit Accumulated Depreciation for the car's accumulated depreciation, 3) credit the asset account containing the car—such as Vehicles, Automobiles, or Cars, 4) credit the account Gain on Sale of Vehicles for the amount necessary to have the entry's debit dollars equal to credit dollars. If the earlier depreciation amounts assumed a salvage value of zero, the gain will equal the cash received.
