i would go and either take YOUR car back and get your title later or call the cops and say that he is pretty much holding your car ransom till you pay him the $120.00. it is all about principal and he is screwing you over dude,,,dont take that from no one man.....knuckle up with him if you have to,hehehehe. good luck with it though, from what i hear so far thats your car and he has no legal recource but to give you the car,keys and title back or its theft....but i am no lawyer so that may not be the case
