You are paying mostly for the luxury - high quality leathers, ultra-comfortable seats, lots of wood, etc. The cars are hand-built, and they take a long time to produce (up to 400 hours for one car). The reliability and performance is much better now that the Germans own them (Volkwagen owns Bentley, BMW owns Rolls). Still, is a Bentley really worth twice as much as a BMW 750 iL or a Mercedes S550 ... or thrice as much as a Lexus LS 460?
