I test drove this today and it is an awesome car, miles apart from the S class of 2009 through 2012.
Responsive, smooth, and agile are words that come to mind. The dash is a nice design that is easy on the eyes.
All the speedos and telemetrics are software designed, not real needles like on the e class. Which is a bit of a change. But nonetheless easy to drive. Also no HUD.

The perfumed air is a nice touch and so are the 9 different colors of interior mood lights. The GL has three. My e has one.

I also felt the front seats were not as wide as the older models and the seats were much more snug. I wasn't falling about as i took some sharp turns.

After typing all this, I feel the best seats are the back ones. If i bought an S, i would ensure I had a chauffeur

One thing i did note was that the tires are run flats now, so no spare. However this did not impact the ride.

 

Good write up! The 14 S class is a very appealing car vs the older models for sure.

 

Saw one on the road yesterday. Looks nice. The LED driving lights are a bit much but otherwise it looked like a nice refresh for sure from the previous generation.

 

saw one on the street too here. it looked better in pictures.
