Buyers frequently need to confirm whether a G550 has the AMG Line package, described as an all-or-nothing option that is the only way to get a factory sport exhaust, AMG body styling, 20-inch AMG wheels, and lettered calipers. The sport exhaust changes tone noticeably in Sport mode, and sellers sometimes conflate the wheels/exhaust with 'AMG.' Threads also flag owners fitting crooked fake AMG badges to G550s.
