"Its a very solid car and really makes you feel like you are in a cockpit. I looked at the S63, but could not justify the 20K price difference when the 550 still runs a 5.4 0-60. From a style perspective, its a car that will always be in the front at the valet.
Pros: comfortable front seats, good steering wheel, venting in the sunroof allows the heat to flow out of the top in the summer (in the actual ceiling). ability to feel the road or soften the ride to feel like a Lexus GS by flipping a switch. Overall, a very solid feel.
Cons: It is expensive, would not buy it without a good dealer behind it. You get what you pay for though as its a very well-made car. The Navigation is still not on par with Lexus and the screen is a bit antiquated looking. The brakes start to squeal at about 50%.
Overall, its a fun car to drive. I love driving it on both the open highway and country roads."
"Still the best-looking sedan on the road, bar none. Fast, quiet, comfortable, and dripping with features and power assists.
Fuel mileage is surprisingly good, 26+ even at 80 mph on the interstate. More like 14-16 in town. Outward visibility is somewhat restricted, owing to the low, swoopy roofline and high belt that gives it the eye appeal. The trunk is roomy, but suffers from a high liftover and smallish decklid (lifts high out of the way, but the opening is pretty small). Gotta watch those expensive alloys with their Michelin rim-protectors, curb rash is an every-present risk. Not as torquey as the CLS55 it replaced, but still a ton of fun."
"I bought a Mercedes from the internet last year (1998 500 SL) and I just loved it. Like driving a cloud. Anyway, in having it serviced recently I did the unthinkable and sat in the 500 CLS. Short story short, I bought one a few weeks later and I'm one month into this fantastic experience.
If you can afford it, I highly recommend it!"
"All excellent except for the price; they could have given me Xenon headlights and fold mirrors. One minor irritation is the visibility for left hand turns. Need to do some neck stretching due to the windshield column interference. My car is a 2008 model"
