Here is my take on the non stock wheels: I once owned a Volvo (i thought i liked it, but i actually didn't) well it had some out of this world world wheels. One of them was damaged. I looked everywhere for the darn thing. Dealer told me that they saw this car and were wondering about the wheels also. To make story short I could not find the wheel. From then on I stay away from aftermarket wheels.
I would like to see manufacturers make some interesting designs.
