Sale of Business Vehicle - how to calculate basis for gain/loss etc.

[teregee]

We purchased a used car in 2015 and put it into service right away.  It was a 2013 model and we paid $39,475 ($19,000 trade-in and $20,475 cash).  We sold this 2013 vehicle in 2020.  We got a trade-in of $17,200. 

This vehicle has an average usage rate of 21%. 

We have always used the Standard Mileage Deduction.  Every year we calculate the depreciation included in the Standard Mileage Deduction.  It totals $3,700.  No other depreciation has been claimed.

How do I answer these questions?
