From my experience/exposure a few months ago w/ regards to the interior...
- the overall interior instramentation/tech was great; felt like a modern interior befitting a flagship sportscar
- the overall ergonomics were very good; some angles/proportions were a bit much
- the overall materials were good; the flat/smooth touch plastics (door-handle trim, center console/dash trim, storage-bin covers, cowl-pieces, etc) were hard & felt rental-car grade, meaning unacceptably cheap & likely scratch/blemish prone
I believe the C7 is an excellent platform, not perfect (and it easily could've been) but very difficult to ignore for it's design/style, performance/handling, price/value. I've never spec'd a Corvette, so I truly have no idea how much (or little) will be added to the ~$52k MSRP to properly & adequately equip to one's preferences & tastes.
Just my 2-pence from the Detroit NAIAS back in Jan/Feb...
