MIB2 has a bigger screen... and maybe if you fiddle with it, app-connect -but you can't see that without power.
Build week 22 in 2015 onwards apparently is MIB2.
Leather was £2615 list, Tech Pack was £1295, Pano roof £995, Rear 90% tints was £95 so about £5k of extras.
Could be other things that you can't see - DCC, lane asist, climate windscreen, high beam assist, rear view camera, advanced telephone, carbon wing mirrors...
I make it £7815 if you stop after you've ticked every box short of mats, bicycle racks etc. Chuck in some Deep Black paint and she's just under £40k fully loaded on a 3 door DSG Mk7 R..
