We were looking for an AWD sedan to replace our 9 year old Honda Accord. We didn't care for Subaru at all. All the other AWD sedans we considered came equipped with low-profile wheel rims, which are big trouble on pothole- strewn roads & frost heaves. We had some concerns about Volvo reliability, having owned Hondas for 20 years, but after 28 months and 32k, this car has been a pleasure to own. The 5 cylinder, turbo-charged engine provides plenty of pep when we need it. We would buy another one in a heartbeat.
Dual climate control - set it and forget it. Longer service interval saves valuable time (7.5k, instead of 3,750 for most cars).
Standard iPod jack. Better fuel mileage. I dinged the S60 for "comfort" due to fixed head restraints, which force short drivers away from the back of the seat, causing back fatigue. The problem is easily fixed by using a pillow or back support, though it shouldn't be necessary on a luxury car.
