Congrats! That thing is beautiful.
I'm interested in a follow-up thread comparing it to your '98 after you put some time in it.
Here is my take after putting about 200 miles on the C6. It is definitely more refined than the C5. When you go over bumps in the C5 you feel as if the suspension is at the bottom of it's travel but in the C6 it's very smooth. It's a bit better in mine because of the electronic suspension too, in touring mode it's very comfortable even on the bumpiest roads (although even in sport mode it's still not as rough as the C5!) The interior looks more modern and has a more expensive feel to it, especially the things like the push button start and the push button to open and close the door mechanism. And having the hatch pull itself down when you drop it is such a cool feature! In the C5 it was hard to close the hatch if the doors were all closed and windows up. I always had to open a door when closing the hatch.
The brakes are better in the C6 but the handling feels like it could be better in the C5, although I don't push my cars too hard in the corners so it could just be my impression since driving the C5 feels more like a raw race car type of a feel while the C6 is more of a cruiser.
When it comes to power, the C6 is definitely a lot quicker! My C5 ran 12.8 at 109.4 in the quarter mile, so it was no slouch, but this C6 is easily down in the very low 12s. I owned a supercharged Mustang GT that ran the quarter mile in 12.16 seconds at 112mph, and this C6 feels that quick off the line and I bet it's trap speed is closer to 116 or 117. I doubt I'll drag race it for a while, the rear ends in the 05s are known to break with hard launches at the drag strip (a friend of mine did just that) and they aren't cheap.
The road noise in the C6 is a lot better, you can actually carry on a conversation! Squeaks and rattles are almost nonexistant, although you can hear a bit of noise from the removable roof. That's the only noise my C6 makes though, no other rattles (my C5 always had a few annoying rattles, especially the glove box)
Gas mileage is a bit better too, even with the bigger more powerful engine, but most of that is due to the 6 speed manual vs the 4 speed automatic (and my C5 had the optional 3.15 axle ratio too, giving it slightly worse MPG) I managed to get 31.1 MPG on my one hour highway trip home from picking up the C6. I did get almost that MPG in my C5 once, but most highway trips were closer to 27 MPG.
