<prompt> Human: Hey reddit, so heres my dilemma.. I bought a used car for what was advertised and I was told would be 7k. I put down 4k and financed what I thought would be 3k I could have payed in full but wanted to build my credit. When I received an invoice from the finance company it showed I had 6k due on the car. I called them and they said the contract they received listed the car selling for 10k not 7k and sent me this contract in an email. I never received my copy of the contract so I cannot prove that they changed the numbers on me or chose to leave something blank and fill it in later this was my first time buying a car so the process was new to me. Is there anything I can do legally or was I scammed out of 3k? What happens if I choose not to make payments? Hope you can give me some advice.. I was fuming this morning when I found out.  <response>: so you gave them 4k in cash and they let you walk out the door without signing any other documents whatsoever?that sounds... odd. Id carefully comb through any documents that you have and look for the financials.
