What this case will turn on is whether or not you and your husband assumed the risk that the car would be faulty. When negotiating the agreement, did the dealer say you were buying the car as is? Did he tell you or your husband that the car had a bad clutch? If these matters were not discussed, the court might find that you never assumed the risk that the car would be faulty, and as a result, the dealer would either need to fix the clutch or return your money for the car.
It would also be helpful if you can show that you and your husband were trying to acquire a working automobile. If you said anything to the dealer during negotiations about using the car for commuting to work or driving your kids to school, it would help your case that you didn't assume the risk that something would be wrong with the car.
You should take a look at the contract you received too. Even though you didn't sign it, a small claims judge would probably consider it as evidence of the terms of your eventual agreement. If it suggests that you and your husband were assuming the risk that the car would be inoperable, a judge might find that weighs heavily against you. If it suggests that the car would be in working order, then you have a decent chance of getting your money back.
