Don’t panic mate, it’s just the way car dealers are “slack” and it’s never personal (they would have to give a monkey’s 1st) to make it personal so don’t sweat it.
As far as your car goes, I’d stick with it and let the missus give MB a ring to chase it up, I wanted the C5 but couldn’t fit my large powerchair in it, I ended up with a different car and while I am quite happy with it I have to say the Citroen C5 Aircross is the nicest ride of any car I’ve ever driven and I’ve driven nearly everything on wheels, so much so that when it comes time to change again I’m considering getting a folding powerchair, just so I can get a C5.
