Business & farm

Thank you.  This is still very confusing, so let me tell you what I think it is:

1) Car bought in 2004 but not used for Business till 2015.  Purchase price was $13,000 in 2004, value in 2015 was $2012.  I used $2012 as TOTAL VEHICLE COST. per the instruction.

2) Per the chart(I used the STANDARD MILEAGE RATE every year) , the depreciation amount was $7814, so I put $7814 in the PRIOR DEPRECIATION EQUIVALNT BOX and $7814 in the AMT PRIOR DEPRECIATION BOX.  (This is the confusing part  --- why put the same amount in both boxes?  It seems like it is asking for 2 different numbers.  Also it states in the note:  "However, the total amount you enter cannot exceed the depreciable basis of the vehicle."  So, should I be putting $2012 in those 2 boxes, as that was the TOTAL COST BASIS for the car entered previously?

3) I used .144 or 14.4% for the business use % of car 31,105 business miles / 216.155 total miles on car. $500 x .144 = $72 for the Sales Price Business Portion. (Traded in for $500 total)

4) On The CONVERSION TO NON BUSINESS USE question, I said NO to "Did you convert this asset to a non business use", as I no longer had the car --- i traded it in.  It sems like you are saying to say YES.  Not sure why.

Sorry for being long winded.  Please set me straight
