Built using the Progen Italia GTB Custon (in-universe McLaren 570S/650S/P14, Trion Nemesi), she is moddified like a GT spec race car, similar to, say, GT3 spec cars that run at Le Mans, Daytona, Bathurst, Monza etc, complete with full spec splitters, wings, engine tuning and interior specs.
The livery being pink, yellow and some white, reminding me, personally, of the McLarens that ran at Bathurst for the Bathurst 12 Hour event over the mid 2010s, even if none of those cars ran this specific livery.
