As usual my timing is impeccable - last saturday I struck my ED deal and Tuesday I see this thread. I just emailed my salesman to see IF the M5 is cosmetically changed with non-retrofittable parts, would they do better on price or offer me some other incentive. Only in the event of changes - I dont care about LED lighting since its an option I probably would not pay for anyhow. I feel like its a reasonable request. Chances are, nothing definitive would be out by March anyhow when I take delivery at Welt.
One thing I noticed, which I think someone mentioned, the M5 front bumper seems to be one integrated piece attached to the hood - Im guessing that would require a lot more work to incorporate the character line into the M version F10. Also, if the hood and fenders remain the same, wouldn't that also mean it could be retrofit?
