Claiming a donated car to charity on my tax returns?

I would like to donate my 2000 Plymouth Breeze to a charity. I am going to be buying a new car and wont get much for the old one. I would rather just donate it. Am I able to claim this on my taxes, and if so, what would I get back for it? I heard there was something new ped that you wont get much, which is fine, but I was just wondering if anyone has done it or has an idea?
