I traded a 2004 350Z on this car. I also drove a Porsche Cayman S before purchasing. The Corvette has unmatched acceleration, but is not as "toss-able" in corners as the Z or Porsche. I am very please with the car and use it as my daily driver in all seasons except the winter.
Even with the magnetic ride controll the handling needs a little improvement. I understand that this has been taken care of in the 2008 model.
