Talks took place with the team's managing director Ryan Story and owner Dick Johnson soon after it became apparent Adderton was serious about running a wildcard in the Great Race.
Initially, the Boost Mobile owner made a cheeky post to Instagram in response to the recently revealed Supercheap Auto-backed wildcard of Russell Ingall and Broc Feeney.

Adderton, who said he didn't want to be out-marketed by the automotive parts retailer, drew the attention of Story, who responded to the Instagram post offering a Ford Mustang.
However, following brief talks, negotiations broke down.
Speedcafe.com understands Dick Johnson Racing seriously entertained the wildcard but decided it did not have the capacity to run a third car.
“They approached us through the Instagram post to say we've got a car. We were like, ‘Okay, great',” Adderton told Speedcafe.com.
“Ryan said, ‘Okay, I'm in, let's make this happen'. Got on a phone call with DJR, Dick Johnson and Ryan and we had a talk about the deal structure, how we were going to make it happen.
“Then just out of the blue they rang up and said, ‘Nah, we're not going to do it', and I'm like, ‘What do you mean we're not going to do it?' ‘We're not going to do it'.
“I said, ‘Okay'. They went weak at the knees and I said, ‘Fine'.”
In the end, Adderton secured a deal with Erebus Motorsport to run Murphy and Stanaway in a Holden ZB Commodore.
Boost Mobile already has a presence within the team on the #99 of Brodie Kostecki.
“We'd been talking to Barry at the same time because we had been looking at multiple options,” Adderton explained.
“No one was planning to do this. Barry had to scramble. I love those guys, and we're going to be long-term supporters of Erebus because of it.
“They stepped in and said, ‘Yeah, you know what? This is good for the sport and it's good for the series. Let's make it happen'.
“I was disappointed that DJR seemed to jump in for the social media aspects of it but had no real intent in doing it. To me that's fairly typical.
“Barry and Betty, they say they're going to do something and they do it. That's rare in Supercars.
“If I say I'm going to do it, I'm going to give it everything to make it happen.
“There's some things you can't make happen. I'm going to do everything to make it happen. Barry took the exact same approach.
“The DJR thing was a fleeting moment in time. It didn't last very long. I didn't expect them to probably do it anyway.
“I don't think they thought we were that serious and were just playing along with it hoping that I'd back out. We weren't backing out.”
