yes you can. you need to take them to court ad provide the court some kind of proof of your good faith loan, cancelled check for example. you may then either put the lien on the vehicle,or re-sue them asking for garnishment of paycheck at the time you are in court. also sue them for any court fees, coping fees, long distance transportation fees and if applicable you can sue them for pain and suffering , like financial hardship. be sure to do all this in one court case so you don't have to go back again for garnishment
