We mentioned the vibration when we were in for service last month. Because the weather was bad they wanted to reschedule so a test drive could be done. Service manager said there was a bulletin for the hood shake, but told me later my VIN was outside the range. Told me to bring it back anyways...
If you dont want to stand out too much, go with black, silver or grey. White was our first choice, but they had a limited choice where we were so we took the Sky Blue off the showroom floor.

Bought ours out of state, and couldn't see drilling holes in the new bumper either. I used the Rho plate for the 2012 Mazda 3. The one from corksport wont work, but with the Rho plate multi mount options it works fine.
