I put $3000 down on a car, and dealer sold car...what am I entitled to legally?

I put $3000 down on a car on a saturday, tol them I'd be in on mon. to pick up car, but car salesman got in late, so we mutually rescheduled to meet wedn. So I go on wednesday and their loan percentage is high and I tell them I want 2 shop around and I'll be back tomorrow (thurs) to finalize things, but the finance manager tells me he's off and to come on Friday. So all day thurs I run around looking for a loan, I get 1 and call the salesperson in the afternoon and leave a message. She calls me at 6pm, I ask if she has the car she says yes, do you still want it. I say yes and she says I'll call you back. She didnt call me back, so I called her at 8pm but dealer was closed. I call her Friday afternoon and she says car was sold without her knowledge. I go to the dealershp and she changes her story, saying she knew it was sold. On top of that the car was still there. They asked me to finalize things on Friday, when I wanted to finalize it on thurs, which is whn they sold it. What am i 2do
