Nearly every feature available from Mercedes is standard on the 2014 G-Class, making it a a high-tech and high-luxury vehicle no matter how you build it.
If you're going for broke, the G63 AMG has very few non-performance features, other than AMG-specific trim and badging. The leather trim is Nappa, and the headliner is Alcantara sueded material. The shifter is AMG's design, covered in wood and leather, and the gauges are AMG-spec, with metallic trim. Piano-black trim is specified in the place of wood, though it's possible to order your G63 as you want it.
There's a lot of standard equipment on the base G550, starting with power locks, mirrors and windows; AM/FM/CD player; and sunroof. It's upholstered in leather, with a heated wood and leather steering wheel, power-adjusted for height and telescopic length. The front seats are power-adjustable ten ways, have memory adjustment, and are heated and ventilated; the rear seats are heated, too, and fold 60/40.
The G550 also has ambient lighting; auto-dimming rearview and driver-side mirrors; stainless-steel running boards; rain-sensing wipers; an integrated garage door opener; and walnut trim. For entertainment, the COMAND controller runs a range of systems through a 7-inch high-resolution screen: it controls satellite and HD radio, iPods and MP3 players, mobile phones via Bluetooth with some voice control for the phone and audio as well as the standard navigation system. There's also a six-DVD changer with video-playing capability; a 40GB hard drive containing maps with space reserved for music storage; harman kardon surround sound; and real-time traffic, weather, news, and restaurant information delivered via Sirius. Mercedes' mobile-connectivity suite, mbrace2, is also fitted, which means in-car versions of Yelp and Facebook, accessible through COMAND.
