When Mercedes-Benz updated its flagship S-class sedan for 2007, it made the car a technology masterpiece. Now, AMG, the German carmaker's in-house tuner division, turned that car into a performance masterpiece. The 2008 Mercedes-Benz S63 AMG is a big, fast European sedan, the kind of car that makes you feel you should be bombing through the Alps on urgent business in Switzerland. As we drove the car during our test, we found ourselves glancing in the rear-view mirror, looking for the diplomats, or spies, who we knew belonged in the capacious back seat.But the car wouldn't let us glance back for long, as there is too much to pay attention to out in front. The S63 doesn't go slow. On a pleasant cruise down a country road we were surprised to find that what seemed like 45 mph was actually 75 mph, and climbing toward 80. Then there are the electronics, from a lovely navigation display to a stereo system with brain-frying audio quality, which demanded our attention, as well. Oh, and did we mention the massage seats? Yes, the 2008 Mercedes-Benz S63 AMG gets everything, absolutely everything, thrown into it, making it almost perfect. Almost.
