the engine in my car went and needed to be replaced, a 'friend' agreed to replace the engine at his families shop for $2500. I transported the car to his home and paid the money. We didn't sign any papers being he was a close friend. He took the car to mechanic in the area and asked him to fix it paid him $500 and disappeared. I was unable to locate my car, didn't know it was left with another mechanic and never authorized any work. After several months i was able to locate the mechanic and was told my bill is $7000 and a lein is on the car. What options do I have? did the mechanic have the right to repair a car without knowing who owned it or if they wanted the work completed? The friend is gone so I have no way of getting the money from him.
