Texas. My neighbor who owns a towing company in my city expressed an interest in buying my SUV that has been down due to needing mechanical repairs. He wanted to take it to his local mechanic for a diagnostic to find out exactly what needs to be done. He told us that he would pay whatever the charges to do so. The diagnostic has been done ($93) but it has not been picked up and the shop is holding it hostage until paid. The neighbor is avoiding my phone calls. Can I pick up my vehicle and leave the shop to go after him for the money? Do I have the legal right to take back my property?
