Hi Mark Just call this number and ask for Sam or email apparently he sold a 18 inch set for a W126 over here in Perth recently. The Price he quoted for 16x8 &9 inch rims was just over 600. I have found people on eBay are asking more than the new price as they still think they are not being made any more. http://www.simmonswheel.com.au/products.asp?index=FR+SERIES
