My Sterling dealer quoted me $1500. 00 for (4) Alcoas and new lug nuts required for the aluminum rims. He also said aluminum rims will be a factory option in the near future. I opted for simulators even though I didnt care much for the looks, but now that I have them I love 'em. The brand is Real Wheels, they come with a lifetime warranty for dulling or fading, they install easily and were a little over $500. 00 with shipping.
