Sheesh, that's just crazy. I don't even like having 21" rims all that much, too easy to curb them and the tires are expensive and short lived. The grey 21s happened to look nice and came "free" back when I got my Perf, but I wouldn't pay $6500 for them. Hell, I wouldn't have paid $3500.Both gray and chrome 21" wheels are $6500 on the Model S Accessories page. Not sure if this is new or not. Haven't tried configuring...
