If you did not have a contract allowing them to sell the car immediately, then you have a breach of contract case against the seller and they are liable to you for your damages. It is unclear whether they can get your specific car back since the buyer was not a party to any contract with you. If the dealer only had contingent permission to sell your vehicle upon financing, then you still have a breach of contract case against them. Try to negotiate a settlement with them and if you cannot, you can sue them in small claims court or you can hire an attorney and sue them in district court. I am sorry that this has happened to you.
I hope that I have helped you, answered all of your questions,
and that I have provided you with useful information.
Please ask more questions if I have not answered all of your
questions.
In the future, if you would like to specifically ask me a question,
you can ask for me in the body of the question.
Please be aware that my answer is not legal advice,
it is merely information. The only way that I am legally
responsible for your legal rights is if you have signed
a written retainer agreement with my law firm.
