(b) Compensation paid by a licensee to a motor vehicle dealer may be an agreed hourly labor rate. If, however, an agreement is not reached within 30 days after the dealer's written request, the dealer may choose to be paid the greater of:
1. The dealer's hourly labor rate for retail customer repairs, determined by dividing the amount of the dealer's total labor sales for retail customer repairs by the number of total labor hours that generated those sales for the month preceding the request, excluding the work in paragraph (c); or
2. An amount equal to the dealer's markup over dealer cost that results in the same gross profit percentage for labor hours performed in work covered by subsection (1) as the dealer receives for labor performed in its customer retail repairs, as evidenced by the average of said dealer's gross profit percentage in the dealer's financial statements provided to the licensee for the 2 months preceding the dealer's written request, if the dealer provides in the written request the arithmetical mean of the hourly wage paid to all of its technicians during that preceding month. The arithmetical mean shall be the dealer cost used in that calculation.
After an hourly labor rate is agreed or determined, the licensee shall uniformly apply and pay that hourly labor rate for all labor used by the dealer in performing work under subsection (1). However, a licensee shall not pay an hourly labor rate less than the hourly rate it was paying to the dealer for work done under subsection (1) on January 2, 2008. A licensee shall not eliminate flat-rate times from or establish an unreasonable flat-rate time in its warranty repair manual, warranty time guide, or any other similarly named document. A licensee shall establish reasonable flat-rate labor times in its warranty repair manuals and warranty time guides for newly introduced model motor vehicles which are at least consistent with its existing documents. As used in this subsection, the terms "retail customer repair" and "similar work" are not limited to a repair to the same model vehicle or model year, but include prior repairs that resemble but are not identical to the repair for which the dealer is making a claim for compensation.
