2008 Mercedes-Benz C-Class C350 Sport 4dr Sedan (3.5L 6cyl 7A)
After test driving all the usual suspects in this category (BMW 3, Audi A4, Lexus IS350), I found this vehicle to have the best balance of style, comfort and performance (not to mention best brand value and brand recognition). After 4,000 miles, I have to say I love this vehicle. It brings a smile every time I sit in it. And it still smells like brand new!
Styling! Best looking vehicle in the class. Build quality is exceptionally high. Also, handling, performance and fuel economy. Stereo system and the command center are very easy to use. Great fuel enconomy for the engine size (and my style of driving).
I wish Europeans would adopt some aspects of the American definition of luxury. Some of the options (like the navigation system) are very expensive.
