If the car is at a car lot then you can do in house financing. Wich will be about 20% intrest lol....but if you pay it off quickly it could be an option i guess.
If you own a car now and depending on your credit you could get a title loan on the car you have now. May only be 500 bucks or may be 2000. depends on a cupple things.
If you have a car already a trade could be possible.
