My parents car is similar Housey, but it has the Premium Pack, COMAND and Widescreen Cockpit. It's Obsidian Black too which always looks good with the chrome on Mercs.
That interior shot has the large COMAND screen, which at least on the launch model meant you got the mouse pad thing in the middle (not that I find it genuinely useful). The initial MY17 model also had the centre console in gloss black, which scratches really easily and is a dust magnet, so wood is better there.
The AMG Line suspension is very comfortable, even on 19" wheels with runflats. I think you'll be impressed with that, my F10 is quite a bit firmer on M Sport Suspension. Hard to fault the 220d engine, it's brisk and the MPG is impressive too.
My two main criticisms are that the UI is quite laggy at times, though yours may have the new Mercedes UX thing, which should be better, and the standard stereo, while clear, lacks bass.
Is this replacing the Polo then? Quite a different league in honesty (Polo being better of course
).
