Thanks for info on NeedsWings web pages, prices more realistic than here in UK. Seems like even they have to pay more for none US keys as ours is listed at $319.95 and yours is $149.95. Still a saving of over $200 is not to be sniffed at. I have a feeling that the OEM key blanks for none USA vehicles come from Mercedes who continue to maintain high European prices. I had to pay £120 (c. $200 then) for a replacement key for my S class Merc 10 years ago.
