In a segment dominated by the RX, the EX is still a bit player in terms of sales, on par with the likes of the RDX, XC60 and once-venerable X3. It might be easy to cast off the Infiniti as an also-ran, but that ignores its principle strength: driving fun, plain and simple. It carves a strong identity on that alone, and other essentials — reliability, safety, cabin quality, value — help its cause. In what's shaped up to be the hottest segment since the crossover boom earlier this decade, I suspect those are good cards to hold.
