mostly because they are made in very low volumes and secondly because its a Maserati and its becomes less exclusive if the parts are cheap, so they charge what they can get. While we all complain about the price of parts and some of the design issues, these cars are not designed on a budget, they are designed to perform in style and put a smile on your face in a way most cars don't. They are also relatively rare, and the parts are a bit exclusive making them expensive, supply and demand. So why is the DBW so expensive? because its part of a system that gets 370 HP out of a 3 liter engine, you want cheap get a DBW for a ford 3 liter V6 which develops 200 HP.
