As much as $300,000 in damage was caused by an overnight fire at a Kitchener car dealership.

Police and fire officials were called to Xtreme Motors at Louisa and Weber streets around 1:20 a.m. Monday.

When they arrived, they found the dealership building full of flames and smoke.

Firefighters were able to put out the fire in time to save the shell of the building, but significant damage was caused to its interior, including several cars that were inside the dealership.

Police are now investigating the fire, examining the possibility of it being deliberately set.

“It’s now being treated as a suspicious fire by police,” said police spokesperson Olaf Heinzel.

“We want to find out who’s responsible. We’re on a busy street. Maybe someone saw something suspicious here this morning.”

The owner of Xtreme Motors, Adnan Khan, says he will offer a $5,000 reward for information that leads to arrests.

Khan says he hopes to get a trailer placed on the lot to give Xtreme Motors some space from which to continue conducting business.

Nobody was injured in the fire.
