I personally find the GT to be a VERY exciting vehicle. Of course, this is my first car that can go 0-60 in less than 15 minutes so maybe everyone else with 'vettes, 'cudas, GTO's and the like may find it to be a slow vehicle, but I get a smile on my face every time I go for a spin.
With the way the interior was set up I think it was designed to be cool on the exterior, and "functional with class" on the interior. I mean, the grocery bag holders on the bottom of the back shelf is pure functionality, while the leather interior is classy.
I think the 2.4L turbo was designed for the SRT but placed in the Cruiser to quell all the talk about lack of power. Also, while I like to go fast at times (more than I thought I would!

), I love to drive the back roads at a leisurely pace with the windows down, the moonroof open and my arm resting out the window.
There are enough aftermarket companies out there that will help you trick out your GT if it isn't fast enough in its factory delivered form. Heck, it'll probably cost less than if you had Chrysler / Mopar do it for you!
