It makes me remember how great I felt the moment I drove away in my first Corvette Dave. The next hour will be like nothing you can imagine or ever feel again. They say having kids is a great feeling.... the first Corvette is better!!! Besides you can use the Corvette to get away from the little texting monsters.
I see you have had some performance in your life so this will be even better for you as your new Z06 simply ROCKS man. Once you figure it out you will know exactly why you paid that much $ for an aluminum/plastic/carbon fiber car.
One nice thing is there is very little noise about the reliability of the tech in the C7 Corvettes. It seems to be pretty sound from the driveline/powertrain management to the body and entertainment/nav control. You will love the PDR. (Get a 64 or 128 GB SD card, format it FAT32 and you're good to go)
I'm liking the Z07 package and will deal with the brake expense when it comes. The hype over the cost is somewhat overblown as my research shows rotors are pretty robust and its unlikely they will need replacing soon for normal use and light track. Ok...i'm hoping that's true..haha
On your brakes... you will be totally sick of the brake dust from the 2nd wash on. I had them on my 15Z. The good news is...there are different pads you can put on that almost eliminate this issue. There are threads on this here and the guys will be happy to let you know which ones if you get fed up with cleaning those nice wheels twice a day and can't find the thread.

But I sure understand being hesitant to buy a used Corvette with Z07 as these brakes would need to be looked at very carefully first. It's good you passed on the chipped up used car and got a new one with no marks. Someone else's marks would have just bugged you endlessly. I bought 2 used Z06s which were both fine, but having the new one now is frankly awesome.
I actually never had a heating problem with my 15Z as I did not track it. It ran perfect for the normal driving and the times I opened it up for a good hard pull.
You will enjoy the different modes....once your tach releases you from the 3500 yellow line. That will suddenly change to 6000 at about 1000km. I watched mine flick up last time we went on a road trip a few couple weeks ago. Of course then.. drop a gear and go!
Remember insist on Mobil 1 oil. The dealer will sometimes put in the other stuff if you do not specify. Hey its free the first 3 times.
Congratulations again
Enjoy your new Z06.
