At the risk of piling on, I also noticed the brake issue. As my colleagues have duly noted, this spongy, "air-in-the-lines" feeling is common among hybrids with regenerative braking, but most hybrids are not massive 4500-pound sedans. For this inconvenience, you get a razor-thin, 1-mpg advantage in fuel economy over a BMW 740Li.
That's the hybrid. The S-class, on the other hand, remains as lovely as ever. Same magical ability to smooth the harshest roads, same fantastic massaging seats with bolsters that inflate with air to keep you in place during turns. As cliché as it sounds, the S-class simply makes you feel wealthy. Let the nouveau riche gallivant around in their crossovers and SUVs, I'd happily be toted around somewhat undercover in a dark grey S-class.
