I have the cross spoke wheels. I agree that turbine wheels look like something from an 80's Chevy, but so do the cross spoke wheels! The M parallel spoke design should update the look of the 850 considerably. The genuine BMW wheels are forged and cost more than double the cast replicas. Anyway I called Discount Tire to get a package price for tires and wheels and was told the replicas are not available (backordered at least 2 months). Plus the sales rep was a little rude. So it looks like the decision is moot.
