In the event of a termination, cancellation or nonrenewal by the manufacturer under this chapter, except termination, cancellation or nonrenewal by the manufacturer for insolvency, license revocation, conviction of a crime or fraud by a dealer owner or failure of the dealer to conduct customary sales and service operations during business hours for 7 consecutive business days, except in circumstances beyond the direct control of the dealer, if the new motor vehicle dealer is leasing the dealership facilities from a lessor other than the manufacturer, the manufacturer shall pay the new motor vehicle dealer a sum equivalent to the rent for the unexpired term of the lease or 3 years' rent, whichever is less, or if the new motor vehicle dealer owns the dealership facilities, the manufacturer shall pay the new motor vehicle dealer a sum equivalent to the reasonable rental value of the dealership facilities for 3 years. Nothing in this section shall relieve a lessee from the obligation to mitigate damages under the lease, nor prevent a manufacturer from discharging its obligations by negotiating a lease termination, sublease or new lease.
