How do I report income from a car I traded in?

Hello,

 

I traded my car in at a dealership upon purchase of a new vehicle and received $1,500 check for my trade in. How do I report it for tax purposes?

 

Also, after I purchased the new vehicle the dealership sent me a check for $1,000 because there was some unreported damage. How do I report that?

 

Thank You.
