I don't think you'll see much titanium in mass-market truck bodies and frames. ;)
The C8 definitely looks better than the C7, and I'd argue the best looking one since the C3. The rear "hips" looked too big to me in the spy shots of the test mules in the camo, but that red one looks better. The rear end designs of the last few corvettes has been an unfortunate evolution into strange and unnecessary angles and I agree that it looks a bit too Camaro-ish. Not my favorite but I won't say it totally ruins the car. I definitely prefer the smoother styling of Ferrari, Alfa, Lotus, etc.
The interior is a toss-up. They've clearly come a long way in quality of materials and fit/finish. Not sure how annoying that row of buttons will be, but it sure seems unintuitive and almost designed to take the driver's attention away from the road.
Styling aside, I think the C8 is going to make a huge impact in the sports car market. 495 HP for the base model is a healthy bump from 460 in the C7, and it will be very interesting when some lap times come in. $60k sure buys a lot of performance. Down the road, it looks like there's more than enough room for a supercharger. ;)
GM also commented on maintenance too, which is often tricky with mid-engine cars:
"Lee also confirmed that the C8 doesn't require any routine engine-out services—often an expensive bugaboo with mid-engined cars—and that the spark plugs and other ignition components, along with the accessory belts that are tucked up next to the passenger compartment at the front of the engine, can be accessed with the engine in place. However, swapping out, say, the oil pump will require dropping the engine."

Hopefully the C8 will spark some innovation from other automakers. Would be great to see Ford and Dodge build something competitive.
