You asked for Nurburgring. That's Nurburgring.
That said, I wouldn't mind seeing races of legitimate sports cars that are identical to what people can buy from the dealer if they have enough money.
NASCAR used to be that, back in the day, but somewhere along the way they lost their soul. Their "stock" cars certainly aren't stock anymore.
I think the Europeans make some attempts at what they call GT racing, but their racing leagues keep failing. I'm not sure what they have at the moment.
