A consumer may waive the right to receive a written estimate if the waiver is voluntary and made without coercion by the motor vehicle repair facility. A motor vehicle repair facility or anyone in its employ shall not make use of the waiver in an attempt to evade this Act. Nothing in this Section shall be construed as requiring a motor vehicle repair facility to give a written estimated price if the motor vehicle repair facility does not agree to perform the requested repair.
