4. What documents should you have to help protect you in a dispute with a mechanic?

To protect yourself in a dispute with a mechanic, you should keep detailed records of all transactions, including invoices, receipts, and estimates. Document any communications with the mechanic, such as emails or text messages, that outline agreements or promises made. Additionally, take photos of any work done or parts replaced, and consider having a written contract that specifies the scope of work and costs. This documentation can serve as crucial evidence if a dispute arises.
