Which asset value do I have to use to calculate depreciation?

I was wondering which value of an asset do I have to use to calculate depreciation, the market value or the original value? For example:

I buy a 20 thousand car with an expected service life of 5 years, the first year's depreciation is 4 thousand dollars. 

The second-year the car's market value is 18 thousand instead of 20 thousand, so the depreciation would be 4 thousand dollars (using the original asset's price), or 3.6 thousand dollars (using the present asset's market price)?

    You always use the original value. Market value doesn't enter into it.

    Original cost less salvage value for straight line depreciation.
