Hi, if I were to buy a classic car and have my logo and business name on it, park it places where it can be seen, drive it places for advertising. Could I write off the full purchase price of the vehicle?

as your vehicle is used exclusively for business purposes, you may generally deduct the full cost of operating the vehicle, other than expenses attributable to commuting.but if you use the vehicle for your business on a part-time basis, you will have to allocate your expenses based on your business and personal use.There are two methods that can be used to compute your vehicle expense deduction for the business use of your car:
Standard mileage rate is generally easier to use and doesn't require you to keep as many records. It will generally be the preferred method if you do relatively little business driving. However, it's not available to everyone.
Actual cost method may result in a larger deduction, particularly with a relatively expensive car. However, the burden of keeping records for every penny you spend on the car may cause more trouble than the deduction is worth., if you use a car 100% for business, you may depreciate its entire basis. If you use it 50% for business, you may depreciate only 50% of its basis.Depreciating a passenger automobile is unique in one very important way: The annual depreciation deduction for automobiles is limited to a set dollar amount each year. The annual limit applies to all vehicles that qualify as ?passenger automobiles.? A passenger automobile is any four-wheeled vehicle made primarily for use on public streets and highways that has an unloaded gross weight of 6k pounds or less.
