WEST VALLEY CITY — A fire at an auto repair shop caused about $100,000 in damage Tuesday night.

The fire started at a shop inside a commercial strip mall at 4669 S. 3500 West about 10 p.m., said West Valley Fire Chief John Evans.

Firefighters kept the fire from spreading to nearby units, though some businesses suffered smoke and water damage.

A car inside the shop was destroyed in the fire. Investigators were still trying to determine the cause late Tuesday, Evans said.
