Personally i would opt for
Sunroof - transforms the car inside and out - quite common
Comfort seats as the original ones look cheap - worth seeking out
surround view
Sun protection - very common
20" Alloys - very common
Rear seats heating / climate if you can find it - very rare in 640d
Heated steering wheel - as above
Head up - wouldn't bother as no m view on non m cars
Adaptive drive also quite rare
Finally a car that doesn't have cheap looking ali trim
Ceramic controls
Digital dash i think became standard on later cars too
Hi beam i have it, never used it
Oh and Harman Karden that was rare on 13/14 cars i think std on 15 cars onwards
You will also find that later 15 cars have a better suspension set up and drive far better than earlier ones.
Also another anal one, 15 plated cars have a larger bore exhaust and looks much nicer than 13/14 cars, also sounds better.
Those options are all out there, just need seeking out, plenty of choice so id be picky if i were you.
