Motorists in East Saltdean woke to find several cars parked in the same road had been vandalised.
Wing mirrors and lights were smashed on vehicles parked at Bannings Vale.
Telscombe town councillor Duncan Ward, who lives on the road, said the boot of his car was kicked in.
He said: "The area is usually quite quiet but one person heard some noise at about midnight on Saturday.
"I think between five and seven vehicles have been affected. I spoke to the police and they said they had already had four reports.
"A couple of months ago I saw a similar thing had happened in Woodingdean."
