The Australian Ford Falcon XA GT was known as the "Chicken Coupe" because its owner, Gordon Stubbersfield, parked it in a barn and protected it with chicken wire since he could not afford to have it insured, the Australian Broadcasting Company reported.
This particular coupe was a predecessor to the design used as the basis for the Pursuit Special (V8 Interceptor) muscle car featured in the Mad Max franchise films.
It was also one of just 120 high-performance models featuring a 330 hp 5.8-liter V8 that could max out at 160 mph.
The Ford Falcon was last registered and started in 1988 before it was left to rot inside a roadside shed in Brisbane.
President of the Falcon Cobra Club of Queensland Troy Postle said Stubbersfield refused to sell the vehicle despite the numerous offers he received from car collectors over the years.
"He was adamant he didn't want it touched — he loved it as it was," Postle said.
It was the car Stubbersfield owned when he got married and he enjoyed talking to people who stopped to ask about it until he died last year.
A 1973 Falcon XA GT Hard Top RPO 83 in fair condition is worth approximately $70,000 while those in pristine condition have a value of roughly $180,000.
The buyer has yet to reveal what they plan to do with the vehicle.
