Can I get a car loan? 18, no job, and no credit?

Can I get car loan. I only need $4500 and I will not have have a job for at least a couple of weeks. I have no credit. I need all info on loans/fiancing because I've found a really good deal on a vehicle and I don't want to pass it up and I'm only 18 so I'm not sure how this all works.
