For what it's worth, I had my heart set on a a set of ED Sprint wheels and was willing to pay the silly amount Ford wanted for it. Then I was told by a tyre place that the wheels are no longer available. I was told the only other option was aftermarket copies which cost $2k for a set plus tyres.
I didn't get such a story from another tyre place, and I got a very reasonable price on a genuine set. It pays to shop around.
