2015 Mercedes-Benz S-Class S 550 4MATIC 4dr Sedan AWD (4.7L 8cyl Turbo 7A)
The Mercedes exceeds the Lexus in quality in all criteria. The Mercedes adaptive cruise is so much better than the Lexus. The Lexus is so slow to react. The brakes on the Lexus were super sensitive. So far this car is heaven. Ask me in a year if I still think so.

It eats tires and brakes, and will cost you more for gas as it is lucky to get 16mpg if you do not drive on freeway every day. Definitely would be the car if you did a lot of open road driving at higher speeds. Lots of power for passing even at high speeds. Quiet and great ride.
