the interior on the benz blows away the interior on the xf, and i kind of like the front formula 1 inspired grille too, and you cannot deny the awesomeness of the retractable hard top! but i still love the exterior looks of my xf, btw you see thousands of benz' but hardly any xf's on the road, that makes them even more special, imo, and saving 20 g's is pretty awesome too!
