There's a huge difference between expecting all to be delivered by November and actually doing it. I wonder how much extra time goes into production - although I suppose that most of the detail will be contracted out.
I believe that the Plus 4 SS which has tested the engine may also have this rear end, so you would hope that the bugs are being ironed out.

This has made me feel unusually bolshy.........
(Not to be confused with feeling Boshly may I add). smirk2
