"It was senseless stupidity. Just random, " he said.
The vandals smashed the windscreen and driver's window.
"It's just a hassle. You have to go through the insurance company and clean up the mess."
The group was "yelling and screaming out" but he could not make out what was said.
The man's wife said she heard the car "hooning around, speeding like anything" before the attack.
A Carmichael Rd resident said she and her husband heard four loud bangs about 10.45pm. When they went to investigate, they saw a group of youths hopping into a white stationwagon before it sped off.
"We thought maybe they had smashed up the bus shelter, because that's where it [the noise] was coming from. Then we came out and it was a parked car on the other side of the road."
The woman, who also refused to be identified, said the late model car was parked outside Bob Owens Retirement Village and was damaged badly.
"They had smashed the wing mirror and bonnet. When I rang the police, they said they had another report of something like that happening."
It is understood the car belonged to a village staff member. No one at Bob Owens was able to comment yesterday.
An attack on a parked car on Devonport Rd was also reported.
Acting Senior Sergeant Owen O'Brien said there were three or four cars damaged across the city and the same group was believed to be responsible.
