I just came back from lunch with my two brothers, one of whom has always had a thing about Corvettes, buying his first one at 16. He never stopped. Now, at 70, he brought his new, fully loaded 2014 Z51 to show off to us. I must admit, it is an impressive car. Apparently there is a butterfly valve in the exhaust for which you can twiddle a knob to adjust how you like your Vette to sound. There are many other knobs that will adjust many aspects of the driving experience all through the drivetrain and suspension systems. It's a good thing I live down a long, dusty road which keeps me from spending too much money on good-looking, expensive cars.
