The luxury brands have converged on a model for success, and for all the vehicles mentioned here, there's a choice of engines, transmissions, drivetrains, and body styles.
The Mercedes-Benz C-Class and the Lexus IS are the most conservatively styled in the group, with sedate, well-finished interiors-and a wild side in their respective C63 and IS-F forms.
The BMW 3-Series is a perennial here, with everything from diesel power to ripping M3 acceleration in the cards.
The Infiniti G37's not far off the BMW benchmark of ride and handling, and it looks better to many eyes, too.
The Audi A4 has grown into a larger body, and spins off coupe and crossover versions as the A5 and Q5.
Meanwhile, the sedan and wagon bring highly detailed cabins and all-wheel drive to the party, though Audi's fantastic S-tronic dual-clutch gearbox is nowhere to be found.
