Sport sedans operate in a gray area where practicality gives way to emotion. A thoroughly rational shopping list of the world's best examples would include the Audi S6, the BMW M5, the Cadillac CTS-V, the Lexus IS-F, and the Mercedes-Benz E63 AMG. But pragmatism, logic, and good sense are rarely the deciding factors when considering an irrational purchase like a $100K-plus, 150-mph-plus automobile. Instead, right-brain values come to the forefront - style, rarity, sophistication, glamour, equipment, image, and, yes, sex appeal. The aforementioned sedans are undeniably speedy and dynamically impressive - but at the end of the day, the M5 isn't much more than a 528i on steroids, the S6 is an A6 that has undergone a complicated heart transplant via Sant'Agata Bolognese, the CTS-V and the IS-F both have relatively humble genetic backgrounds, and the E63 AMG started life on the same assembly line as 75 percent of the German taxi population.
