Anyone here get rid of their IS only to regret it and buy another one? I traded my 02 manual for an 03 350Z. I guess I am getting old or something. I miss the build quality, comfort, stereo, and general feel of the car. I dumped it because I was not satisfied with the power. In hindsight, I could have probably made it as fast as my Z for the amount of money I lost on the trade and money I will lose if I get rid of the Z this soon. Any thoughts?
