Where else can you be terrified - and get a clean car?
The Halloween shenanigans at the Waves Carwash in Phillip have attracted somewhat of a cult following.
Think getting a car wash while scary characters including, shudder, clowns terrorise the occupants of the vehicle trapped inside.
What's not to like?
This year, the Halloween car wash will take place over two nights - on Friday, October 25 and Saturday, October 26.
But, good to know, early in the evening, there will also be a kid-friendly version, that is more about lollies and dressing up than all the scary stuff.
Waves Carwash marketing manager Maleeha Chowhan said each night from 7pm to 8.30pm would be the family-friendly sessions with candy distribution and a best-dressed competition.
Once the sun went down, it would be time for the scarier stuff.
Adults are also encouraged to dress in their finest Halloween costumes to be in the running for prizes. They include a three-month pass for unlimited car washes.
And Waves ambassadors, retired Raiders legend Jarrod Croker and his wife Brittney Croker, will be taking part in all the fun, dressing up and helping to judge the costume competitions.
Maleeha said entry to the Halloween car-wash was $30 per car - so she encouraged friends to get together and carpool for the night.
And the ticket does include a carwash.
The event is also selling tickets online for the first time.

The Halloween car wash is held by Waves at Phillip only every second year - which allows for a lot of planning to make each one more terrifying than the last.
Canberrans can expect to have the bejesus scared out of them this year.
"This one is going to be epic," Maleeha said.
"We have put our heart and soul into it."
