There are two trims available on the C-Class: Sport and Luxury, which each receive enough distinctive details to look different from each other on the road. You can have nearly every feature available on either model, so you won't miss much by choosing one over the other.
A very long list of individual options are available, including (some of the highlights): heated front seats; a Harmon/Kardon Logic7 sound system; iPod/MP3 interface; voice control; and COMAND hard-drive-based navigation/infotainment system.
A range of packages are also available, combining some of the most common options into popular configurations. Appearance upgrades such as illuminated door sills, a roof spoiler, a painted sports grille, and upgraded wheels are all offered as standalone options.
Standard equipment even on the base C250 includes dual-zone automatic climate control; Bluetooth hands-free calling; Bluetooth audio streaming; cruise control, a HomeLink universal garage-door opener; and a power tilt/sliding sunroof. There's also the next-generation mbrace2 telematics and concierge system, which now includes a mobile app for remote horn and light operation and Valet Protect functionality, as well as Speed Alert, Driving Journal, and Curfew Minder services. There are also apps for Google Local Search, Facebook, and Yelp, among others.
C63 AMG models bring a host of performance upgrades, in addition to a long list of interior features including power steering adjustment, power heated AMG sport seats, Harman Kardon 12-speaker sound, a power rear sunshade, and special AMG instrumentation with a race timer.
