I went to MBWorld on Friday to see the SLS.
It is a fantastic looking car, very long nose but quite short once you get past the A-pillar.
The interior was a very high standard, lovely leather and aluminium with some proper chunky switches and dials. The gull wing doors are very easy to use, however if you are not a 'normal size' (i.e. a bit fat) then getting in and out could be difficult. The very high door sills will be scratched very easily which is a shame.
The cabin is a bit too cramped for my liking, I don’t think its much bigger than the SLK inside which is a shame for such a big car, it did feel a bit claustrophobic. The middle of the roof has all the hinges and supports for the gull wing doors which means the middle part of the roof dips down a bit which could be a pain if you are very tall.
Started it up and it does sound very nice, the exhaust note is the best I have ever heard from an AMG, cracking and popping even in neutral when revving it up, it must be 0.00001 dB under the legal limit!
The B&O £4000 sound system option was very good as well, but not sure it was £4000 worth, probably half that.
Unfortunately no photo's, but it was the same car pictured in this thread.
Its located in the Maybach lounge which is closed to public, but you can just about see it if you stand at the main Maybach door and look to the left.
They also had a rather nice CLK CTM Cabriolet which was rather tempting...
