Bought CPO 2014 S550 with 49k on odometer. Silent engine, stunning interior and a bunch of safety options. Distronic Plus, Active lane assist, Night Vision along with 360 degree camera makes driving super safe. The active seats are amazing and the 5 different settings for massage are well designed. So refined, so technologically advanced it makes others wanna be MB. Cruise down a darkened highway knowing your vehicle is scanning the distance for humans or large animals, as it maintains the lane and speed all the while a hot stone massage is lowering your stress level. Nothing short of amazing.
