Interior wise, Mercedez Maybach seems to have done phenomenal job, but exterior is disappointing.
The other Mercedez Pullman, is just either E Class or other smaller Benz just streched, but looks alot better than the Mercedez Maybach.
The real competition, however, is between Maybach and Phantom.
By exterior stylingwise, Rolls Royce is simply stunning. Its amazing how they have retained its original grill style after 100 years or so. You can see even the hood shares some styling from the original Rolls Royce, made almost 100 Years ago.
This beauty is classic, timeless jewel, no doubt.
