Is it really worth the change?

Facelift Front End with Adaptive Bi-Xenon Head Lamps
Seat Material
Trim
Panoramic Sunroof
N62 Engine with X-Drive, and TPM
Crystal Tail Lamps
SCA trunk
BMW Assist

i'm sure i'm leaving out some other things, but if i had the 4.6is i would just keep it and upgrade it.
