It’s the latest in a series of WAU Commodores offered through team partner Lloyds Auctions while it is an active race car.

According to its listing, the car will be delivered after the completion of the 2022 Supercars Championship and, unlike previous WAU auction offerings, will be sold complete with its Bathurst race engine.

The car will come in the specification it completes the 2021 Bathurst 1000 and dressed in the owner’s choice of livery from either the 2021 or 2022 seasons.

The Gen2 cars are slated set to be replaced by Gen3 midway through 2022, although there remains significant speculation that the Gen2 machines could race on until the end of next season.
