A burned-out car in Maxwell Avenue was set on fire a second time on the early hours of Sunday morning.
The car was burned out some months ago, but has been sitting on a property since it was torched last year.
Central West Police District Chief Inspector Peter Atkins said the car was set alight at 4am on Sunday morning.
"We believe the car was already badly damaged and was re-lit," he said.
No other damage was caused during the blaze, which was promptly extinguished by NSW Fire and Rescue brigades.
