If you purchase a car with autotrader can you make payments?

I like a car on the website. It is for 2,000 without all the other charges including the license fee and all that other stuff. I was just wondering if it's possible to buy the car yet make payments on it. Instead of paying 2,000 flat out can I do monthly payments of 200 or less? Or even weekly payments? I live in MA and the dealership where the car is located is in NH.
