I'm not arguing, but are you sure what you saw in the lot wasn't an overland (non summit) charcoal color w/saddle?
I could very well be totally color blind and do apologize in advance if incorrect here, but I've seen a few M. Grey's live...and your pic looks darker. Maybe the light was different. Anyway, my top 2 choices are mineral grey and brilliant black. I bought black and love it but if they screwed up and M. Grey showed up at the dealer. I'd still be pumped up. Re: your opinion of the non-matching dash/door trim and seats, I have not seen this in the wild w/the WK2's I've seen (M. Grey or otherwise), but others may have seen different.
