Yes, you will need to report all depreciation taken in the years the car was in service for your business.This really has nothing to do with useful life but has everything to do with business mileage deductions that you taken while you used the vehicle for business. In those mileage deductions are built in depreciation amounts referred to as depreciation equivalents.
On page 24 of this IRS link, it addresses what the depreciation equivalents are for the past for every year since 2000, How to get the depreciation equivalent, you will multiply your total mileage for the year by the depreciation equivalent rate listed in the table. You will need to find out how many business miles were claimed in each year of service and multiply by the rate listed for that year. Then you total up all the depreciation calculated for each year and that is the depreciation recapture you need to report.
