Its a nice process, the problem is you still end up coming home with a BMW.

One-month wait is the downside
I was so anxious to get my car back
However, you wait for your car if it's custom ordered regardless
And total time from ordering to recieving it is about the same
Driving in Alps and on autobanh is so rewarding though, not to mention proper break in
P.S. I would never buy another european car without ED
I think BMW, Audi and Benz have great ED programs
