I drove the S550 here in Los Angeles last night. I stopped by the dealership just to look at it, but was surprised when they asked if I wanted to drive it. I must say, while it is no doubt a very nice car, I was a little underwhelmed by the overall driving experience. After reading countless reviews and comments on this forum, I expected a much more "life altering" experience.
It is certainly a quick car, but not a rocket ship. The interior is well put together and flows great. If you have ever owned the W221, you'll be right at home with this one.
It's certainly a comfortable ride, but isn't as quiet or as smooth as I had hoped. In Los Angeles potholes and streets, sound resonated through the tires and into the cabin more than I had wished. It's as quiet as my current car, but certainly not more quiet.
IMO, if you are coming from a W221 or a vehicle that is older than 3 years, this will be light years ahead of what you are used to. If you are currently driving a large luxury sedan that is late 2012 or 2013, the W222 S Class won't feel like leaps and bounds ahead of the competition. I wish it did.
The demo car didn't have MBC, exclusive leather, the air freshener installed, so I'm hoping I will like mine much more when it comes in next week. If not, I'll have a Anthracite on black with black poplar, MBC, sports 1, premium pkg, air freshener, distronic plus, surround cam for sale. Will know in about 9 days
