Tickford Racing's championship-winning Falcon FG X, which has been restored and sold, has returned to the track.
Mark Winterbottom's 2015 title-winning Ford was placed on the market last year following a long restoration project.
Tickford posted an image of the car to its social accounts, with the car to be shaken down by Cam Waters.
Waters is on-site at Winton Motor Raceway with Tickford teammates Thomas Randle and Declan Fraser for a rookie day.
The Tickford spearhead will take to chassis FPR 1217 as part of a handover day at the Victorian circuit.
Winterbottom won nine races in the car in 2015 en route to his first championship.
The new Team 18 driver remains the Ford squad's only Supercars champion, having outlasted Craig Lowndes in a thrilling championship fight eight years ago.
Title glory for Frosty in 2015
The car debuted a year earlier in a Falcon FG package, with Winterbottom winning four races.
The Falcon carried on following Winterbottom's championship, with Waters himself racing the car towards the end of 2016.
FPR 1217 is the fifth-most successful Supercars Car of the Future chassis of all time, and third-most successful COTF Ford behind the Scott McLaughlin DJRTP04 Falcon FG X and DJRTP06 Mustang.
Its first four wins came as a Falcon FG, Winterbottom winning twice at Pukekohe, at Winton and Darwin.
Converted to FG X panelwork for 2015, Winterbottom claimed nine wins across Barbagallo, Winton, Townsville, Queensland Raceway and the Sandown 500.
Winterbottom last drove the car at Barbagallo in 2016, before it was raced by Waters, Jason Bright and Richie Stanaway across the next couple of seasons.
The car then returned to Winterbottom’s hands for the final rounds of 2018 to end its main game career, and the driver's time with the Ford squad.
Tickford restored the car over a 12-month period, and put it on the market last year.
The Campbellfield squad will run all four Gen3 Ford Mustangs in a test day at Winton on Wednesday.
