You've got a problem even going to small claims court unless the money to purchase the car was a loan and you were supposed to be paid back at a certain time. This is because if you were engaging in an illegal act to circumvent the law, the law will not step in to help you. As is often said, you must not come into court with "unclean hands" in order to ask the court to help you clean up the mess.
In addition, how can you drive a car without insurance? How would you get an insurance policy on a car which is not yours? Did you intend to drive the car without a license? Have you been driving the car without a license? These are questions you should think about before going to court. You are under oath, swearing to tell the truth under the penalty of perjury. I'm sorry about the problem but this was not a good idea.
