They actually have an s550 at the local dealer, it is Black with Black interior (which I do not like as well) ...the car does not have all the interior options (16 way seat adjustments etc.) so it is not fair to compare it to the 760 yet, as it was it was not very impressive but the salesman did say that this was a demo and it was there to give an I dea of what the car looks like. Loots of room both back and front and they did go back to BIG seats up front which I like.
The outside is pretty cool,it is different from the others in it's class but in my oppinion not a knock out...could be the color combination .
Did notice the controls for the seat adjustments on the doors were cheap looking and felt like "cheap plasstic",no fancy at all , I was surprised by this.
I'll have to wait to see a fully loaded one in order to make a decission but as of now I think the best car in this class is the BMW 760.
