The Skyline R32 GTR's were banned from Supercar races in Australia after they completely dominated the Australian V8 Holdens and Fords. It won 3 seasons straight before the V8 ego's couldnt handle it anymore and just basically booted them from the series.
I've always had a dream where they continued to dominate more and more through the R33 and R34 series. If that dream were true then maybe our cop cars and taxi's would all be Nissans rather than Fords and Holdens
