Brendan Scott and Emma Hearn have created their very own Grease Lightning to raise funds for cancer research.
And just like the original Grease Lighting - the car is a bit of a shitbox.
That's because the Leppington couple are taking part in this year's Shitbox Rally.
Mr Scott said he and Ms Hearn decided to take part in this year's event as they had both lost family and friends to cancer.
"We wanted to do something proactive to help raise funds for much needed research," he said.
"This will be our first rally together, however, I have participated in two rallies with my mum where I learnt how great the rally experience was."
Each year the Shitbox Rally takes hundreds of competitors on a cross-country jaunt in old, rundown cars to raise funds for cancer research projects.
The route is different each year but often takes place in regional locations.
Ms Hearn said the decision to call the car Grease Lightning was an easy one.
"With Shitbox Rally our vehicle is only allowed to be worth $1000," she said.
"Choosing our vehicle was easy, we wanted a Holden, white and mechanically okay.
"And here our replica of Grease Lightning was born.
"We chose Grease Lightning as our theme because its fun, most people recognise the lightning strikes as part of the movie and during the rally we have to dress up most days, so we thought it would be fun to dress up as Danny and Sandy [from the movie Grease]."
Mr Scott and Ms Hearn hope to raise 8000 and are already more than halfway to their goal.
Ms Hearn said they were looking forward to the race.
"We will travel to Alice Springs to the start line, where we will head off on our seven day adventure in the outback, north to the Gulf or Carpentaria, then head south east and finish at the Gold Coast," she said.
"We are really excited about this route, travelling through the outback with another 250 cars, while raising funds and awareness for the Cancer Council."
Mr Scott encouraged other locals to get behind them or consider registering for a rally themselves in future.
"When you join one of these rallies, you become a part of the rally family," he said.
"Every one of us has a friend, or family member, we are taking part in the rally for.
"It's so great to be able to remember your loved ones with other people who understand how tough battling cancer can be.
"It really is an experience like no other."
