<human>: To start off with, yes I am a complete idiot. I am kicking myself so much right now. But please help this idiot not get into any more trouble. 
   I bought a used car from a "dealership" (contract says consulting corp) for 800 dollars Friday. With tax and other fees, the total came to 1000 dollars. I paid the guy 1000 dollars cash, and signed some forms, which at the time I thought was a bill of sale. The dealer printed out temporary plates, gave me copies of the papers I signed, and a temporary vehicle registration and let me on my way.
   On the way home, the engine light came on and when I looked at the engine, it was covered in oil. I tried talking to the dealership, but they told me that the sale is "
as-is" and I cannot do anything about it. So I considered this an expensive and valuable life lesson and planned to sell the car or scrap it. The dealership said they will give me the title on Monday.
  But later, I looked at the papers again, and turns out the form doesn't say anywhere I paid for the car, instead says "balance due on delivery". 
  What can I do? Do I have to pay the dealership again?

Can you give me a shortened version of the text?
<bot>: Idiot rushed car purchase, paid full cash for a broken car, left with no title or bill of sale, now scared if he has to pay the dealer again.
