2013 Volvo S60 T5 is now available with AWD.....by far the best seats in the industry, care-free maintenance program and the more powerful of the base engines as compared to the opposition.
The BMW would be your most agressive and sporty choice. It all depends on what you want or need. The Benz has become mainstream and diluted, while the Lexus is at the end of it`s life cycle, not to mention the rather boring interior.
Volvo has 0.9% financing and care-free maintenance program, plus 5yr/80000km warranty. The base model comes with the T5, 250hp and 266pd/ft of torque. 0-60 in about 7 flat.
