Thanks! I was torn between the Model X slipstreams and the 21" Turbines. I love the look of the dark wheels on the silver but it was tough choosing between the two wheel styles. My car was in for service and I was given a Model S with 21s as a loaner. They looked great but they rode just a bit too rough for me.
Here are some pics of the rear, sorry the lighting is pretty bad. If you'd like any additional shots, let me know.
