You can expect a few moans and groans from an older vehicle, for sure....just like me! But...any abnormal noise is a sign of excessive wear, or damage. The under-car noise you hear is most likely a suspension bushing that has deteriorated into oblivion. I would raise the car up and have a look-see at all of the suspension components, including the shock bushings, and the shaft u-joints.
These old gals have some miles on em now, but they were never whisper quiet. Guys at the dealerships always HATED to see a Corvette come in with a noise complaint, since there was usually never a solution.
The dash noise might not be a "normal" noise....most don't have noises in the dash, unless there is a definite problem.
We would need more info, and a more detailed description of the noise(s) to help pin-point an area to check.

Besides....that's why they put radios in them, and made the roofs removable!!! LOL

Mine doesn't have many squeaks or rattles, and after the new weatherstripping very little wind noise! A lot of those noises in the dash are probably the results of "Bubba" doing work on it!

Well, the shocks are new and the undercarriage looks really clean but, yes, I'll have a mechanic look at it when it's in the shop for something else.

And the dash or bezel noises are really strange. You wouldn't think noises would come from there. I know the radio has been replaced, and that might've loosened things up.

I got a quote of 1,000 bucks installed for a basic CD stereo with 2 in dash and 2 rear speakers, and that's before the recommended bezel replacement (another $200 thru Ecklers). I passed. It wouldn't even have been that great a system, and for 1K? No way.

Being clean underneath won't preclude it from having worn or damaged bushings....always worth a look-see. Could also be the exhaust loose somewhere and rattling when you hit a dip/bump...not that that would EVER happen in a Corvette...
Have you checked to see if you have a spare tire back there? If not, the tub could be bouncing around, making noises.
So many possibilities...so little time...

It does have the spare tire intact, yes.
