Update! I've placed an order. £333 deposit and £343/month for:
M140i Shadow Edition Edition
Alpine White
Cognac leather
Gloss black trim
Automatic
Adaptive M Suspension
Front Parking Sensors
Heated seats
It's a deal of the century and one that I would have regretted not exploiting. You only live once and in two months there won't be a 6 cylinder 3L hatchback avilable to order new.
My GF won't appreciate the sound of a throaty engine firing up on the drive way every morning!
