The S6 has the same generic design as the S5, but looks good.
It does have a few nice enhancements, like ventilated and heated front seats, a useful decent size "frunk" seems to have a sunroof in the video, but not sure UK will be getting it as with the S5, shown everywhere with a sunroof, but this one is UK registered, well just have to wait a little longer.
This is the car I was told (by my local MG sales manager) would arrive earlier this year, but it was beaten by the S5, it just shows MG don't even tell their sales teams what's going on!
It definitely has an interesting & nice looking interior, I'm sure over the coming weeks/months, lots more details will be revealed.
