When I got my 2006 C6 in Oct 2005, the brakes were horrible. They squealed terribly every time I stopped. I immediately switched to ceramic pads. A few months ago I needed a brake job and knowing I was trading the C6 soon I put the original pads back on, uuuuggggghhhhh. Sqeul, sequel, squel. I sure hope they have improved this on the C7.

As much as we all hate it, brake squeal is nothing more than a high frequency vibration of the brake pad against the rotor as you begin to depress the pedal. This condition can almost always be fixed by doing a PROPER brake job, and not just changing the pads and calling it done. The ceramic pads have a different friction characteristic and either didn't cause a vibration or changed it to something out of our audible range.
It just sounds like you may need to find a new mechanic....for your brakes anyway.
I ordered my car with the Painted Black Wheels option. Changing my C7 brake pads to Hawk High Performance "ultra low dust" pads will one of the first mods that I'll do. Did that on my 2010 Camaro just to reduce the brake dust...huge difference.

So, are you saying that many of the early C6 Z51s had bad brake jobs from the factory and the others didn't?
Is it a Z51? They had a penchant for squeaky brakes. My '05 vert (non-Z51) brakes never squealed.
Non Z51. Lots of complaints back then, that is why I did the ceramics. I'm most likely trading and I'm in the first consensus so I'm not really worried about this car, just hoping not to have the same issue with the C7. I always have my car serviced at my dealership.

Actually, there are two different squeals from brake pads that annoy people. One is due to the brake pad material, and the other is due to the pad backing material.
The former is generally caused by high performance pads that are fairly hard compound (and, unfortunately, destroy rotors faster). The squeal from these will happen at all speeds the moment the brake pedal is touched. Rarely do pads like this make it on a street car from the factory.
The latter is different and usually only heard just as the car is rolling to a stop. The reason for that is the resonance frequency of the pad finally lowers to the point that we can hear it at the lower wheel speeds. The squeal is still happening at higher wheel speeds, we just can't hear it because the pitch is way too high.
Solutions for the former is a different pad material altogether. The latter? Some pad backs have little damping pads on them that are suppose to prevent the squeal. Or you can add pad grease to the backs of them.

You are absolutely correct. I just didn't feel like going that in-depth. Regardless, I always spray "Brake Quiet" on the pad backing of every brake job I do....and never have a customer complaint. (The brake quiet remains tacky and keeps the pad from vibrating.)
