Okay, this at least, maybe, answers why we haven't seen the AU XR8.
THE Ford Tickford Racing AU Falcon driven by Glenn Seton and Neil Crompton in the 2000 Bathurst 1000 is set to be restored to its former glory. Known as
www.v8sleuth.com.au
The car was converted to BA Falcon body panels and remained as such until the beginning of this restoration.
I'm sure there are other V8 Supercars PD could use. Though I'm not sure off the top of my head where Championship winning Falcons like the Marcus Ambrose and Russell Ingall reside. Next Fords would be the FG and FGX models to have won Championships.
The muti- Championship winning DJRTP #17 of Scott McLaughlin would make too much sense.
As for a Holden. There are plenty championship winning cars. Probably any Peter Brock classic should be first and foremost. Next, a Whincup car over a Mark Skaife car. Just because Skaife had been affiliated with XBox in the past.
We'll see if we ever get an Aussie race car in a future GT game.
