The handling was pretty good the ride as mentioned earlier was better than the Caddy also was quieter. the only thing I did not like was the width kinda felt tight on the elbows towards the door. The interior was nice but a bit too much black plastic, the switch gear were of good quality and feel.
Go test drive it definitely worth it will suprise. The 2007 should be out in a couple of months.
One thing that ticks me off is usually when a car mag compares the G6 GTP its to a Acura TSX or a similar more expensive car not a fair review! My GM card is maxed out so that is one definite for the G6 as far as getting cash off.
Also the Cadillac comparing it to is same body suspension as one current Deville.
