I have a manual transmission CTS-V and having a manual is a significant performance disadvantage these days. A 10 speed auto transmission will shift much faster than a 6sp manual driven by anyone even a professional, and it has more gears to sit in the sweet spot of motor torque/horsepower. If I buy another fast car it will 100% be an automatic. One thing I like about manual transmissions though is the reliability and maintainability. Problems with automatic transmissions can basically total a higher mileage car.
