I had a 2006 QP Sport-GT and loved it. I learned how to properly drive the duo-select and never had any issues at all. I did avoid stop-n-go traffic, and NEVER EVER reverse up a hill....that gets the most clutch slippage. I agree with others, if you drive the duo-select right, listen to the pump prime and learn what it is supposed to sound like, and maintain the car - it will treat you right. In 2007 which is the last year for duo-select, they made some system improvements...so it's the best year to get if you want a manual trans-axle in a 4 door sedan. I think it's very cool.
