"Can't believe it": Mostert on maiden Supercars championship win

After 13 seasons racing in the championship, Chaz Mostert can still hardly believe he’s now the Supercars champion after he claimed his maiden title on Sunday.
Mostert finished second in the Adelaide 500 Grand Final after an incredible finals series, with his three wins during the finals enough to overcome Broc Feeney, who suffered a lap 1 crash and engine failure that ultimately saw him drop out of contention.
At 33 years old, Mostert helped his team to their first drivers' title since Mark Skaife in 2002 on his way to a first career championship for the two-time Bathurst winner.
After a night of celebrations, Mostert revealed to SEN 1170 Breakfast that the reality of their achievement hadn’t sunk in yet.
“Honestly, I still can't believe it,” Mostert told SEN 1170 Breakfast.
“I feel quite numb in emotion, which is really weird. I don't know how to really process it at the moment.
“I'm just so honoured to be part of the organisation, with Walkinshaw Andretti United (WAU) and all the guys and girls there, and the hard work and dedication they've all put in over so many years.
“It's so cool to see it all. For all of us to be able to get this win is something pretty special… it's going to take some time to reflect.
“I think the best way to sum it up, time creates doubt.
“I came into the Supercars Championship… just before 21, and if you keep the speed up, you've got a long career ahead of you, and you hope that one day you achieve success like this.
“I've been lucky enough to win Bathurst a couple of times, and put one good weekend together which has been so special but winning a championship, it's a lot of hard work, grit, and determination and obviously, the finals format still creates amazing pressure.
“To be so consistent over the last three rounds of the fast car, and fast team, and faultless car, it's been amazing to be able to, and honoured to, drive that car.”
Pulling back the curtain on a big night of celebrating the win, Mostert plauded the contributions of WAU co-owner Ryan Walkinshaw.
Throughout the race, Walkinshaw was seen shaking his head in moments where he thought Mostert was overdoing it, but, as to be expected, was ecstatic with the victory.
“It's just unbelievable to have him here… they took a punt on me quite a few years ago to get me involved with the team, and it's just so cool to see it all kind of pan out quite well,” Mostert said.
“Everyone celebrated pretty hard last night, I actually haven't seen Ryan for about 14 hours, probably.
“I don't even know where he is at the moment. Last time I saw him, he was on the roof in the garage.
“We have one of the most passionate team owners, probably in the whole sport, and it’s an honour to drive for this team and our other shareholder owners as well.
“I haven’t seen the footage back, how he’s shaking his head with how many laps to go or not, but look, you do your shaking your head, I’ll do the driving, and we’ll see what pans out the other side.”
