Crooked Car Dealership Research (Houston)

I am looking for other individuals with similar stories to prove my case. I was ripped off and lied to by a very well-known car dealership in Houston. I can’t post the name of this dealership but if you have a similar story with any dealership, please reply to this post.
This is my story:
I co-signed for a car in 2010. Eleven days later, the dealership called to let me know that the loan had fell through. I returned to the dealership with the car and the other person who I had cosigned for. At this point, I was not interested in signing another contract. The finance guy did not let me return the car. He claimed that the sale and the financing were two different things. The sale was already sent to corporate and they could not take it back so I was obligated to sign another financing contract with me as the primary. I asked what would happen if I left the keys in his desk. He said that if I did that, I was going to be charged $300/day for storage of the vehicle until I returned to sign the financing contract.
I was not sure if he was telling the truth so I asked to speak to the manager. After discussing this matter for what seemed like about four hours, the manager confirmed that I had to sign another contract. I signed a second contract because it seemed that I had no other option. The dealership put me as primary on the loan knowing that the car was not going to be for me and that the person that the car was for was not related to me.
When I found out that they had lied, I contacted the salesman that got the sale and nothing was done. Then I went to speak to the manager (this is a different manager than the one I was presented to before) and he says that since he was not there, he is not even willing to look into the matter. I contacted the finance company, and they keep referring me to the dealership. . . I need to gather some evidence against these crooks. If you have a similar story, I look forward to hearing from you.
