You mean for racing, or for sale? For sale, no way. For racing? It's possible, but I think they would use the Mondeo. It needs the marketing push more here, and is closer in size to the other new cars. Hell, the damn thing is only 5 inches shorter than a Falcon. New cars are so big
But I would love some crazy RWD V8 Focus in Supercars. I hope they move away from the V8 only formula in the long term though (heresy, I know) to something more like the old Group A regs they ran under in the 80's.
Edit: Holy shit, was that a real ad? Damn Canberra Milk, you love your motorsport at least.
