If you owe the mechanic money and have not paid them they certainly can hold the car and I am sure by now you have heard from a creditor at least. If you make no attempt to pay off this debt then yes, the mechanic can sell this car, but you should have been notified. If you weren't then it's against the law! The title on the car can be gotten easily enough. If you have not paid off the bill and have never received noticed from a creditor or lawyer then this mechanic has stepped over the line. I suggest you see a lawyer about this if the car is fairly new.
