JACOB Ross woke up to a burning car outside his Sun Valley home last night, the third time it has happened in a month.
Police is investigating the suspicious fire that started before midnight and completely gutted the white VS Holden commodore.
Mr Ross said he knew who was lighting his brother's cars outside his Cairncross St home.
"About three weeks ago they burnt another VS and a VT station wagon before that," he said.
He said he was worried the fire would spread to the tree above the car and then to his house where kids were sleeping.
Neighbour Ainsley Josefski stopped the tree from catching alight by putting out the blazing car before the fire fighters arrived.
"I was down in my room playing (Playstation 4) and all of a sudden there was a big orange glow from outside," he said.
"I looked out the window and there was a big fire ball."
Mr Josefski ran across the street in his boxer shorts to Mr Ross' home.
He grabbed Mr Ross' hose but it was too small.
He ran back for his hose and used it on the fire.
"I covered the tree in water too because I thought it would go up," he said.
"I was standing right beside the car in my boxer shorts with stuff exploding around me."
After putting out the fire Mr Josefski went back to playing Need For Speed on his Playstation 4.
