Status or street cred? I'd head to head Mustangs and Falcons from 1987-today. Only when the Mustang GT gets to 2005, is when it's in the same league as the Falcon GT(I'm excluding the F6 and Shelby Mustangs for a reason). As a North American, I knew of Skylines since 1989. Australia grew up with them. The Falcon was dead and buried in the USA until I started seeing V8SC on Speedvision.
And at a time when teams were able to run AWD in World Challenge(RS6, A4 Quattro, R34), MotorEx were just importing Skylines. The racing world knew of Falcons from visiting Bathurst and surfers. The USA buying public unfortunately did not.
Makes me also wonder if the V8SC can be used in a USA series like the RX8 GT is used in the Bathurst 12H. I wouldn't be surprised if people start buying them to do club races in the USA.
Any way, Australia need to buy the Mustang. If it's selling well, who knows, we may see a new Falcon in the future.
