So, after seeing the video ... Detailing is superb! Inside & outside.
The overall exterior styling is too conservative yet too busy at the same time. Lights graphics is just too tacky for my taste. Especially the sequential "fire-up" feature. Christmas tree, anyone?
Interior is extremely techy-looking. Very cool. Too cool. Just cold. Not very inviting & not appearing cosy at all. Although the details are amazing.
Styling, design, features, appearance etc caters very much to the tech-savvy buyers of luxury large sedan. New luxury? It could be. But there are still quite a lot conservative baroque-loving customers out there (based on S-class sales figures). And still quite a lot of those who want something in between.
I'm eager to see, hear, read (and later also test) how it drives & rides. It looks like a serious attack on 7er & S-class & LS et all - all at the same time. As promised.
