With a quality interior and a V-8 engine, the 2007 Volvo S80 shoots for the luxury sedan segment. It hits pretty close to the target with a comfortable cabin and interesting safety gadgetry. But its stereo is only tuned for front-seat passengers.
Volvo's stereo interface looks good and works well. Too bad Volvo doesn't offer Bluetooth cell phone integration, which would make the keypad in the car more useful.
The steering wheel of the S80 has audio controls on the right and buttons for the adaptive cruise control on the left. You can set your follow distance with these buttons.
