Budgetplan, welcome to the forum. Sounds like you are doing everything right with her. I HIGHLY recommend at least a clear bra on the front. Took a little longer for me to get mine, but couldn't be happier with the protection it offers. No rock chips since installed. My wife just got back visiting her brother in FLA and saw her first ZR1 up close. I won't post the pic she sent, but the person that owned it already had scratches and rock chips on the front end. If I'm spending $140k for a ZR1, I'll spend the $500 for the clear bra. Oh wait. I have the Z51 and did it.
I also have the automatic in the year that has had the most reported problems and can happily say that she is running fine with no issues. I'm in the sport setting 99% of the time.
Good luck with your new C7. Enjoy it. Post some pics when you get a chance.
