Final answer:
The question asks to calculate depreciation for a car using an unspecified 'method 2', but insufficient details are provided to perform the calculation. Accurate depreciation computation requires data like the initial purchase price and the specific depreciation method's rules.
Step-by-step explanation:
The question revolves around calculating the depreciation for a V-8 sedan in its third year of use, using 'method 2'. Unfortunately, the specific details required to execute method 2 were not provided in the information given. To calculate depreciation with a given method, one would typically need the initial purchase price, the rate or method of depreciation, and the number of years for which the vehicle has been used. Without this specific data or a clear understanding of what 'method 2' entails, it's impossible to provide an accurate calculation for the car's depreciation. For a detailed computation, more information would be required regarding the vehicle's initial value and the rules of 'method 2' depreciation.
