That would be the Mercedes Maybach 62. It's the brand new ressurection of the famous Maybach luxury brand. It makes Bentleys etc. looks like a Toyota Corolla in terms of luxurious comfort.
I arent from the US and havent seen any pictures of the launch, but the car was black i think (saw pictures of it being shipped), and was carried across to NY on the QE2 cruise liner. It was launched in America as that is anticipated to be its largest market.
