Price
– · The maker prices this in CHF: 19,990 retail, with a stated pre-order price of 17,990. The shop also renders USD 24,967.51 and 22,469.51 under ?currency=USD, but both are the same 1.249 multiple of the CHF figures, so that is the storefront converting at a floating rate rather than a maker-set dollar price. Recording the converted number would let exchange-rate drift enter the catalog as a price change, so priceUSD is left null and the maker's own CHF figures are kept here.
