Hate to kill a buzz, but the Tuxedo Blue interior will be a treatment on the dash and door panels and a Shale (Light Tan) seat, much like the Envoys have Tan seats and Black dash and carpet, but it would be sweet to have color matched interior/exterior like they used to on the '00 LeSabre
As for 5.1 - NO -it is a 9 Speaker harman/kardon sys like BMW has, and as for Bluetooth it is questionable, it would make OnStar hands free calling obselete, but you can get a HEATED :o woodgrain steeringwheel as a dealer install later in the model year
