Repair-shop disputes generally come down to the same things: the written estimate, what was actually authorized, and the final invoice. Organize those facts and get a free letter outline; the full demand letter is in the $39 Case Pack.

Illinois's Automotive Repair Act requires specific written authorization before any repair work exceeding $100 begins, after the shop discloses a statutory rights statement that the customer signs. The customer chooses from three options on that form: request a written estimate before work begins, allow work to proceed but require a call if the price will exceed a dollar figure the customer specifies, or waive an estimate entirely and let the shop set the price. Once authorized, the repair price may not exceed the estimate (or a customer-set price limit) by more than 10% without further consent, which can be given orally if the shop notes the caller's name, date, time, and phone number on both the estimate and invoice. A consumer may waive the written-estimate right voluntarily, but a shop may not coerce a waiver or use it to evade the Act. Every repair facility must post a statutory customer-rights sign. Estimates involving disassembly must separately disclose the cost of reassembly if the customer declines to proceed.
