Obviously, taste in wheels can be all over the place. It has always been my opinion that your wheels are one of the few areas that should show some contrast to the design and possible modifications to the body of the car. I know I am going to show my age now, but the new look of painted/plated grey or black wheels just does not do anything for me. If I am going to make an investment in new wheels, I want them to stand out, add some bling and not have a stealth look to it. This is just my opinion and I respect others that may disagree with me.
Also, if you are going to be concerned about the ability to clean and detail the wheels, Rich brings up some valid points. So, if this is a concern, you might not want to look at the stock C5 Z rims, painted or polished. Because there are more spokes on a Z rim, there are more areas that dirt can get into and you have to clean on them than you would have on a good aftermarket plain 5 spoke rim (chrome or polished). And there are some very nice plain 5 spoke rims out there to choose from.
Well, good luck in your wheel hunt. I am sure you will come up with something that you and Carrie with like.
