The 450 is one of those rides that has a bunch of smushed nose, cheek, and lip marks all over the windows from people trying to get a full peek inside. The diamond-stitching provides the initial I-have-to-touch-it feeling, but it isn't until you actually step inside and ride through the night that you fully experience the cabin. The unexpected fine details are really what make a passenger inside a luxury vehicle feel important. The layered texturing, the precise contrast stitching, the underlying runner lights along the door and dash, and the lumbar massagers in the front seats all make you feel like you've elevated your status in the world.
