Well....all depends. Who do you need to sue? Can't sue the previous owner, cause it's up to you to check REVS to see if it's under finance. However, the previous owner should of told his finance company that he was selling the car, or something to that effect.
Personally, I'd speak to someone about it. If your going to sue, best that you sue the RIGHT people, rather than waste more money by going to court and losing. ALSO, once the small claims have ruled on the matter, it is final. There is no appeal.
If you go to court, makesure you have FACTS on paper. Try and get that person's name who said it was clear. Go back to transport department and get that info. Facts mean everything in a court case....you ain't gonna win squat by saying "I was young and stupid".
I don't want to discourage you from getting back what you lost, but make sure you do it right the first time. Sometimes it's best to cut your losses and start again.
