The dealer is in breach because on one of the other documents I signed it says I have 48 hours after financial rejects my submission to decline or approve my documentation to be submitted for approval again. I declined but the dealer submitted it against my will. But before that they had told me I was approved and gave me to the keys to the car and everything, but then they ended up calling me a few days later saying that financial declined my offer. That's when I decided to return the car because basically it wasn't mine because of the refusal but they declined taking the car back and resubmitted my offer. Sorry for not explaining better.
If you believe a contract was breached, you sue the other party whom you allege caused the breach.
Your remedy, if there is one, awaits you in an Arizona court room.
Its not a breach because YOU alone declare it a breach.
Only a judge, after a trial on the merits has been held, can declare the contract breached.
But, before you think that'll be easy, read your contract.
The contract more than likely has gotten you to waive your legal remedy in court, and requires you to seek redress in mediation or arbitration.
While, the lender retains its rights to sue you for non-payment in court.
You might start dsicussions with the lender, and see what the lender says.
You could also try speaking with the dealer general manager or owner.
Good luck.
