Section 179 bonus depreciation for vehicle

If you buy a vehicle over 6k pounds for business purposes, it is my understanding that you can appreciate 100% of the total cost in the first year.

A few questions:

1) aside for the bonus depreciation, is there regular depreciation each year as well?

2) what happens if you need to sell it 2 years later? Is there a recapture of the bonus depreciation?

Thanks!
