Johnny,
I think you'll like the Z06. I used mine as a daily driver for about two years before turning it into a racecar and found it very easy to live with.
The car does sit relatively low compared to most other cars on the road, but I concur that I wouldn't raise it. Before I lowered my car, I only rarely scrapped on driveways. What actually hits the ground is the plastic air deflector under the nose. This is a three piece unit, one each side and one center one that deflects air up into the radiator. The center one is hinged so if it hits something it will just rotate. The side ones are pretty flexible. They are also inexpensive (all three total less than $100) and easily replaced with about six small bolts hold the side ones on and I think two holding the center one on. I never once hit the actual nose on anything, though it is low enough that you could run it into a curb parking in some spots if you aren't careful.
