I am calculating the maximum depreciation in 2010 for a new automobile used 100% for business. The vehicle was purchased July 2, 2010 for $28,000.

I am calculating the maximum depreciation in 2010 for a new automobile used 100% for business. The vehicle was purchased July 2, 2010 for $28,000. The taxpayer elects section 179 on the vehicle and it was also the only property placed into service for 2010. I initially thought that the whole $28k would be the max. Depreciation under section 179, but I would think that the fact that it was purchased July 2 would factor in. So I'm torn between $28,000 or 6/12(28,000)=$14,000. Please clear the fog.
