Delivers the sonic goods

Opting for the Bowers and Wilkins speaker system automatically includes an iPod controller, which cleverly gives full track and artist info on the screen, as well as DAB radio and the already-standard single-slot CD player.

Voice control, a CD changer and digital and analogue television options are also available at extra cost.

Sound quality is exactly as a Bowers and Wilkins system ought to be, with plenty of
drive in the mid-range, a fast, expressive touch with complex rhythms, and most impressively none of the leaden, boom'n'bang bass that can afflict some cars with powerful boot-mounted subwoofers.

Instead, low-frequency support is taut, agile and properly placed within the car, while voices have excellent character and presence.

Overall, its a real achievement, and well worth ticking that option box for.
