well, i did it. i traded the 04 with 38k for the 06 with 7k. i got exactly what i wanted this time, the impulse blue with blue leather. there are some interesting details, some i knew, some i didn't, that are different on this one. first, the ones that are commonly known: dead pedal, different font on gauges, LS2, bigger brakes (wow, what a difference!), faster seats, exterior changes. now for some that took me by surprise: a button on the center console to lock/unlock the doors, buttons on the steering wheel are now lighted, the mph/kmh light is not so bright and has more of a blueish hue (the 04 was so dang bright!), the compartment under the stereo is now a slide out ash tray, and slightly different design of the blinker/wiper stalks. it's kinda weird that gm made some of these changes. i don't think going through the trouble of adding a door lock button is going to increase sales. i guess it's good to see they are doing some things just to make their customers happier. anyway, just thought i would share.
