Why aren't they using an Infiniti Q45 which actually uses a Bose sound system inside instead of this Lexus LS? Either way this is impressive technology which I would like to have on my own car. This would look even more extreme on a full size luxury SUV like a Cadillac Escalade, Lincoln Navigator, Land Rover Range Rover, Lexus LX, or Infiniti QX. How much does this suspension system cost anyways???
