Fire crews were first alerted to a blaze on Malta Avenue in Ashmont at 11.25 on Thursday night and spent 45 minutes putting out the car.

Fire crews were alerted to a second, separate car fire just after 12.30 on Friday morning.

The second car was set alight in the reserve along Blakemore Avenue in Ashmont.

Turvey Park Fire Station commander Jeff Edwards said crews spent about 40 minutes at the second fire.

Mr Edwards said both cars were totally destroyed by the flames, which he believed had been deliberately lit.

He said he didn't think the two fires were linked.

"It's just a shame that happens, for anyone who loses their mode of transport around at difficult times as it is," he said.

"To have your mode of transport destroyed or blatantly vandalised makes life much harder than it should be.

"[They were] deliberate, malicious on both accounts of that."

A Blakemore Avenue resident whose house overlooks the reserve in which the second car was destroyed told The Daily Advertiser car fires were becoming a common occurrence in the park.

"It's pathetic ... I feel sorry for those poor people who lose their car," she said.
