I have the transparent top that has been quiet so far by just latching it down properly and keeping the seals clean and treated. Your top may just need an adjustment and the fix that has been used on some of them that have squeaked, not a hard job, told you about it before, did you do anything?
As for the brakes, did you break then in properly? Most likely not, after all it's a $50K car and it can be driven any old way the owner wants, right? My guess is that you have glazed the pads by improper break in diving. Simple job to remove the glaze and then break in your brakes properly. I'm nearing 40K miles on my C6 and they are starting to show some wear but I have never heard a brake squeal/squeak yet.
Also, my breaks squeak. They've squeaked forever. Am I wrong to think a > $50K vehicle should not be squeaky?!?
