Gift from parents (money was reimbursed)

My mom and dad bought a car for me as a gift. They live in Puerto Rico and flew to the US to buy the car for me. He paid $10,000 cash and then I paid about $18,000 with a personal check and then they reimbursed me the money with a check from their business (that they own). I received a letter that form 8300 was sent to the IRS for the $10,000 cash. Is there anything special I have to do when filling out my taxes?
