Surprise my boyfriend by paying for his car loan

My boyfriend has been amazing to me. I was bullied all my life and he saved me from self destruction. He's one of the most hard working men I've known and I want to give him one of the best gifts of all. I want to help pay off his car so that he can start saving up more and he won't have to limit himself to a tight budget because he always puts away money to pay off his car.   I want to give back to him because he saved me from the trauma of bullying and has taken care of me since Day 1 of our relationship.     Please help me make this dream come true
