The differences between Sport and Luxury models carries through to the interior as well. The Sport wears a three-spoke steering wheel and either matte aluminum, burled walnut, or black maple dash trim in sparing amounts, and it has more drab plastic than the Luxury, which dons burled walnut, chrome, and a four-spoke wheel. Overall, the C-Class has the more angular, less flowing look that's been introduced in many of the brand's recent models, with a well-organized cabin with large and clear gauges, plus distinctive-looking door panels and, unfortunately an audio-system interface that's just a little too overwrought with identical black buttons. Somewhat awkwardly, the audio and navigation display is tucked behind a hinged dash panel that sits up while the screen's in use; it works in some vehicles (like the Cadillac CTS family), but it feels cobbled on here.
Also part of the C-Class family is the high-performance C63 AMG. Building on the cues of the C-Class Sport models, the C63 is hard to mistake from the outside, as it looks far more aggressive, with wide performance tires on huge AMG wheels, along with unique AMG spoilers and trim throughout, inside and out. And if it's not enough, the raspy AMG exhaust system comes with twin chrome tailpipes.
