I think you will love Imperial Blue in the sun. Looks great from these pics:

I am getting the same color in 335 Sport Line and am coming from Orient Blue E46 as well.
BTW, My ED is scheduled 1 month after yours - 11-May pickup and also planning Nice dropoff. Be sure to keep us up to date on how you car is getting along on the way back to the states so I can use it to estimate my re-delivery timeline from Nice (a bit worried it may take longer than Munich dropoff).
