It started a little before 3 a.m. at the L&L All in One shop in the 1700 block of Niles Road.
When firefighters got there, flames were everywhere. Firefighters said it was tough trying to get them under control.
Tuesday afternoon, restoration crews were busy trying to secure the building.
“I usually come by here almost every day and you know, this was the first place I bought my car from,” said James Campbell, of Warren.
The building that used to house D & J Auto is now a total loss.
“I never knew I would see this place burnt like that,” Campbell said.
The estimated damage to the property and its contents is around $500,000.
Even though the fire department first got the call around 2:45 a.m., they believe it had been burning for quite some time.
“That fire had a significant head start and the firefighters did their best to bring it under control but it was just too far gone at that point,” said Warren Fire Chief Ken Nussle.
Firefighters used about 100,000 gallons of water to attack the flames.
The fire was so overpowering that it took down trestles and a back wall.
The cause of the fire is unknown at this point, but it remains under investigation by Warren fire investigators and the state fire marshal’s office.
“Any time you have fires early in the morning like that, a lot of times it does tend to be suspicious. Given the fact the fire gained some headway also and there wasn’t a call for quite some time, but that also could be because of the time of day,” Nussle said.
