Some drivers seats have a fore/aft clunk as there are some small plastic bushings that have excessive play.
Clean the door and hatch seals and coat w/dielectric grease.
Install jacking pucks
The headlight motors have a weak gear. Have yours been upgraded?
I added a battery charging wire and have it routed to the fender vent. When parked longer than a week I plug it in.
You didn't mention brake fluid... I flush mine every two yrs.

Thanks all for your comments, I am going to do the brake fluid with new C6 Z51 Calipers & Pads/Rotors later this year. Appreciate the insight!

Good deal, replace the 4 soft lines with steel braided ones while you are in there (if you weren't already). My stock rubber hoses actually looked okay and were still pliable but it is much better hitting the peddle and feeling that nice solid braking feel with the new lines and fluid!
