I'm not sure if I'd consider the Miura a supercar simply because it's what became the present V12 line from Lamborghini, like the Murcielago, which I don't consider a supercar.
Of course 50 years ago or so things were to be considered a bit differently.
Then again there still were some race cars drivable on the road, which probably would make those super cars. Who cares, just two days ago I was wondering if I prefer a shocking green Miura or an orange one.
