Most probably sold as seen, you have very little comeback. The fact that you're stating that 'as a woman i no noting about cars' has nothing to do with the sale, and is pretty condescending to other women. Also, you should never buy a used car unless you've had it thoroughly checked by a knowledgable person, like your mechanic, and fully testdriven it. Do you even know if the seller had full title on the car to allow a legal sale? Finally, if you're as clueless as you say, is it possible that it's actually your garage that's trying to pull one over on you?
