Price
– · Price on request. The maker states an average budget of EUR 15,000 for a bespoke SB05, rising above EUR 30,000 depending on materials and finishes, and excluding VAT. That is a budget guide for a made-to-order build rather than a price for this configuration, and the case material is one of the things that moves it, so no USD figure is recorded.
