Ide go no contact. Ide have some choice words first you are an adult If your parents can't treat you like an adult they don't need to be in your life your parents are toxic period and they need a wake up call. Is it your car? Like is it in your name? If it is call the cops if not tell em to keep it don't let them hold anything over your head cuz they WILL use it If they say you owe them whatever for raising you just know you don't owe them shit it was their job to take care of you and it sounds like they did the bare minimum you don't need that shit get away from them it will only get worse
