Has anyone here ordered a custom Brompton online? How long does it take from the time you order it until it arrives?

I'm thinking of fairly standard black S1E. Will likely get a Brooks seat and Kojaks on it. Given how standard this is, maybe I can get this from the showroom of one of the local dealers.

One thing I noted on the Bike Builder is that you can't choose the colour of the Brooks saddle. I'd prefer a black B17 special, but it appears from the graphic that it is a Brown B17.

I will be putting black fenders on afterward, since they only have the silver finish on the bike builder. As well, will build a wheel around the Sturmey Archer 8 on my own.
