A luxury car dealership in north Queensland has suffered "major damage" after a fire broke out on Tuesday morning.
It took half a dozen fire crews about two and a half hours to have the blaze extinguished at Townsville's Mike Carney Toyota Lexus dealership.
Fire investigators were called in after the flames were put out about 9.30am.
Acting fire station officer Clint Craperi told the ABC the showroom was heavily damaged.
"We have multiple cars, which have obviously been on fire," he said.
"Plus there's been partial ceiling collapse within the premises and obviously substantial smoke damage but we have saved a large percentage of the building."
Police said the area was gradually being returned to normal after earlier evacuations and a street closure.
Police and firefighters said it was too early to tell if the fire was suspicious.
Businesses have been evacuated and a major road closed as crews battle a fire tearing through a car dealership in Townsville.
The blaze broke out at the showroom just after 7am, forcing the road closure and the evacuation of nearby businesses, including a large homemaker centre.
A police spokeswoman said there were fears about the spread of toxic smoke, prompting officers to block off Duckworth Road in Garbutt.
Fourteen firefighters in breathing apparatus were attacking the flames, focusing on the roof and ceiling space, a Queensland Fire and Emergency Services spokesman said.
"It's a large fire and they're just working to extinguish it at the moment," he said.
Paramedics were also on scene.
