Firefighters are on the scene of a fire on the roof of one of the buildings at Germain Ford at 7250 Sawmill Rd. near Billingsly Road in Northwest Columbus.
No injuries have been reported.
Everyone has been evacuated from the area.
Crews had to go into defensive mode because the fire is so large.
Employees were asked what they saw, but investigators say the cause of the fire is accidental and started on the roof.
The roof was under construction, and they were using a circular saw.
Potentially millions in damage, but no cars were damaged.
The majority of the fire was inside the parts department.
