Scott, $150 is not really that bad as trim and interior items usually run a bit more expensive than the usual consumables. I called the dealer here in Dubai with those numbers and he quoted US$300 EACH ! after discount. I think there is a blue leather 500E in the boneyard here I can look at if you wish.
