Hi Adam,
I was told if I wanted black or champagne, I could get it in 1-2 weeks, but as I went with red, I was told it would more likely be within 3 months.
One month after ordering, it has still not got a chassis number, so I think it is unlikely it will be here within 3 months. I went with the N-Connecta version though.
It is always best to ask your dealer for the estimated times, but even they may be wrong.
