Purchased the Volvo 2012 S60 T6 after owning a 2011 BMW 328i for 13 months (bought in June 2010).
I can say the Volvo beats the BMW in every area.
The S60 is a very fun car to drive, the interior is very comfortable well layed out and easy to use.
The safety features are first rate.
We test drove both the T5 and T6 but like the T6 much better, it just has a better feel on the road and the T6 is much more smoother than the T5.
This is a great car for the value, with many items that come standard vs. others like BMW and Audi. Engine uses regular and the 5 year/50,000 mile maintenance care is excellent.
I highly recommend this car.
The BLIS (blind spot system), City Safety, the 300HP inline 6 that can run on regular gas.
The incredibly comfortable seats.
Does not have those troublesome runflat tires like BMW uses although you can get that as an option.
The seat lumbar control should be automated not a manual turn nob for this price of a car.
Back side vents do not seem to allow alot of air flow.
