I second this comment about ride quality and cabin quietness. I bought top of the line navigator (Black label L) costing over $130K . Driven very low 10K miles in last 2.5 years and the interior rattles and squeaks and makes all sorts of noises like a 10 year old vehicle. This is not expected of a flagship top of the line model and is very disappointing. Sending it to the dealer today in hopes they will be able to adjust / tighten body panels and trims in the cabin to make the rattling noises go away. As comparison my 7 year old 7 passenger Audi Q7 is still very quiet and has no rattles inside the cabin. I hope this post is being read and taken seriously.
