Want to buy used 2008 Honda. What's a good down payment?

Hey everyone, I need to buy a car asap. I'm currently working and can afford monthly car payments of about $300 dollars / month. The reason why I want a used car is because I plan on going to law school soon (fall 2017) and will no longer be working. Therefore, I don't want to get stuck paying a car during my law school years. I saw a 2008 Honda Civic for 8,000. If I give a 2,000 down payment, would it be a good deal? I have no credit but my father is willing to co-sign for me. He has very good credit. Any advise would be appreciated. Thanks
