Car scam , small claim court

Hi guys!

Did anyone had similar situation, I have bought car from a guy and he didnt mentioned certain hidden defects which could not be detected at first. Is there any chance to ask for refund and to take him to court ? As clearly he lied and didnt tell me all the issues in the car as even the mechanic at first didnt notice. If I wanted to buy car which is not usable I would go on dump yard. Can anyone share if had similar situation or to give advice ? As I gave my last saving to buy a car and now its not safe to drive it. Many thanks
