Before you take your car in for repair it helps to make a list of the repairs needed. The repair shop can then inspect your car and estimate repairs. The repair shop must give you a written or verbal estimate on repairs and the final bill cannot exceed more than 5% of the original estimate. Always ask to see the damaged or worn part and return them to you in the box of the new replacement part at the time you sign the work order. After inspection have the repair garage dispose of parts as needed or retain for further inspection.
