Sales rep commuter
12k business miles with a moderate cost base
Useful when the standard mileage method might beat an average-cost sedan even after adding tolls and parking.
Result: The standard mileage method often wins when annual vehicle costs are controlled and the business-use share is meaningful but not extreme.
High-cost vehicle year
Fewer miles with larger actual costs
A useful check when repairs, insurance, or depreciation make the actual-expense method more competitive.
Result: Higher actual costs can close the gap quickly and occasionally make the actual-expense method the stronger deduction.
