No, it is not because it comes with a huge price tag or because it is not in production anymore but because Bentley will only be offering a limited amount of them or at least that is what the new rumors are suggesting.
It is believed that Bentley might be thinking about bringing the Bentley Azure convertible back into the market although a limited number will be available. Car and Driver reported that according to Wolfgang Durheimer, they might build 20units of these vehicles.
Of course, you can also expect these 20units to come with a huge price tag. Although they did not confirm it yet, people has already estimated that the vehicle will most likely come with a $1million price tag.
It is believed that the new convertible will be based on the Mulsanne. Bentley has yet to officially confirm the news yet so take it with a grain of salt.
