Sold a car we took the standard mileage deduction on for 2 rental properties. Do I use the total Prior Depreciation Equivalent or only the portion for each house?

The Prior Depreciation Equivalent is requested under the "Vehicle Expenses" section in both of my rental properties.  I don't know if I use the total miles (miles driven for both properties) to calculate the prior depreciation under both houses or if I use the only the miles driven for that specific house.
