Drivers will park at CWA Park on Saturday and settle in for a rough night's sleep to raise money and empathy for homeless people.
It's the first event of its kind in Griffith, and all proceeds will go towards Linking Communities Network and Fusion Riverina.
Linking Communities Network deputy CEO Kirrilly Salvestro will be curling up in her car and getting a taste of what it's like to sleep rough in the winter.
"A lot of people are really struggling with poverty in Griffith at the moment," Mrs Salvestro said.
"After they've paid their rent there's no money for food or electricity. Imagine being a parent and not being able to feed your children."
Linking Communities Network have had 1633 homeless and at-risk people knock on their doors for help over the last financial year, and Mrs Salvestro says those number just keep growing every year.
She said she's seen a particularly noticeable spike in the number of older single women and young people who can't afford to put a proper roof over their heads.
"Young people find it difficult to find housing because of their low Newstart allowance and the cost of rent in Griffith at the moment," she said.
Several former homeless people will talk about their experiences at the Sleep In Your Car event on Saturday.
Those who can't stay the whole night can still come for the event from 4pm to 10pm, where there'll be dinner and activities.
