V8 Supercar $550,000 AUD
Audi R8 LMS $720,000 AUD
Lamborghini Huracan GT3 $735,000 AUD
Honda NSX GT3 $750,000 AUD
That's hardly "twice as much as a Supercar".
Whether it's a GT3 race car or not, a Ferrari, Porsche or McLaren is still a Ferrari, Porsche or McLaren. They hold their value rather well AFAIK.
Well it's a Ferrari, Porsche, McLaren etc. Of course it costs a lot to repair. That's hardly newsworthy.
Porsche Carrera Cup cars for example cost plenty to repair with genuine Porsche parts, yet still form a strong grid year after year. With the used examples retaining strong resale value and racing on for decades at national and state level.
A spaceframe Mustang GT3 with fibreglass panels would be cheaper to repair for those wanting to run that. While the teams aligned with manufacturers (Mercedes, Audi etc) wouldn't have too many complaints about repair costs.
The depth of manufacturers of the GT3 class simply cannot be matched. It is by far the best way to get Audi, BMW, Mercedes-Benz, Honda, Aston Martin and others involved in the Supercars series.
Unless you would prefer to watch a Ford Mustang Cup, Sandgroper?
