I tried this powerhouse after driving BMW's for 10 years. More power than you will ever need (3 sets of tires in 18 months) but still an MB and not a BMW in drivability. Total brake failure (fluid drained out) in the first two weeks didn't help with impression but it was fine after that...no maintenance issues. Front fender is ripe for destruction on high parking bumpers. Traded recently for a winter car (S550 with 4Matic) but will go back to an S65 or BMW 7 series soon....
Seat needs the BMW alternating pressure pad treatment and accessories plug in should be easily usable
When I started driving, it was very uncomfortable. When I got on the road, the car started slipping. Then it stopped slipping. So I went and drove home to my hometown, Chicago, IL. When I arrived, I turned into my street and my back wheel started drifting. It almost crashed but luckily it did't. The fuel in my tank was OK and it was better then my other car. It looks good but i will never rely on that car anymore. As soon as the weather is better I'll go and return the car. It was not ery fun to drive.
I have owned Mercedes for the last 40 years, and this car is absolutely the most poorly built and least reliable. All others were fine. With 9500 miles, mine has loud squealing brakes, a backup camera that is unusable due to poor optics, Nav map display "jumps" constantly, worse than my hand held $80 Garmin E-Trex. This is the most irritating item of all, and Map must be turned off at night to prevent annoying distraction. The car pulls rt. on 95% of the roads.
More interior room than S500. MPG is very good on highway avg approx 26-27 mpg
Bigger side view mirrors. Have a backup camera that has enough resolution and contrast to be usable. If Lexus can, why can't MB?
This is my 4th Mercedes Benz in 5 years and happy with all of them especially the S550 class equipped with optional versatile features. I have had problems with the computers once in a while but Mercedes take cares of them well. My daily driving experience is great but you have to watch out the gas consumption especially I am driving a 4matic all wheel drive. Watch out the auto gear shifting as sometimes shifting goes to lower gear when shifting to "D" mode.
Dynamic driving is one of my favorite but the pulse mode needs to be modified to a much stronger one but not to the extent of making the driver fall to sleep.
Back bumper needs to be painted well, very thin paint applied over the plastic type bumper, seems like money were spent most likely on computers and some areas of the exterior parts were overlooked.
