Many of the features that are standard on the GL550 are options on the two other variants, such as leather seats, auto-dimming rearview mirror, navigation system and electronic parking aid. All GLs have airbags all around, the PRE-SAFE system, keyless entry, alarm system and vehicle theft tracking. The GL350 and GL450 both have an 8-speaker CD/MP3 stereo, birdseye maple trim, and halogen headlights. The GL550 upgrades these to standard harman/kardon 11-speaker CD/MP3 stereo with SIRIUS satellite radio, burl walnut trim and adaptive bi-xenon lights. Premium packages, available on the GL350 and GL450 bring popular options to the lower trims. The Premium packages, for example, add an auto-dimming mirror, COMAND navigation system, a stereo with hard disk drive, power-folding mirrors, a power-liftgate and SIRIUS satellite radio. A rear-seat DVD entertainment system is an option for all three GLs.The options list for the GL550 is pretty short, as it already comes standard with all of the options available for the GL320 and GL450. Active ventilated front seats are available as is birch trim instead of walnut, and premium Nappa leather upholstery.
