Since there's little to no room in the cabin to carry anything, I'm frequently opening and closing the bonnet. I found the Rings were located right where I would naturally place my palm to close the hood.
When the dealership had to pull the rings off as part of the 3M clearbra install, I had them left off. I liked the look enough on the front that I also them "erase" the rings off the rear deck as well.
I find the missing front rings to be much more convient for closing the bonnet. The only drawback is all the gawking by cars drving past now trying to figure out what kind of car it is. The only visible Audi badging are the center caps on the wheels, and the engine logos/rings, none of which leap immediately to view on the road. Kind of fun.
The opinion of friends and on-lookers was overwhelmingly in favor of leaving the rings off the hood. So I did leave them off and I have to honestly say that I think it adds even more mystery and even further intrigue!
I prefer the rings on. It shows that I agree with Audi in the design and manufacture of this car, and I think it's the best that I can get within the price range or even out of the price range.. Audi continues to do amazing things in the Automotive world and is being rightly noticed. The rings are a symbol of their attitudes and success.
