2007 Mercedes-Benz S-Class S550 4dr Sedan (5.5L 8cyl 7A)
The horsepower is on par with my '02 S55, the 7-speed transmission is so smooth and accurate as to be barely there. The updated computer systems are easy to learn, my wife likes the sirius and panoramic roof. The kids like the rear seat redundant controls for the windows, front seat and sunshades -- (7) electronic shades versus (1) previously! Only two complaints -- the standard leather should be upgraded and the electronic door closers should trigger easier like the '02.
