Charlie, it appears that my Series 4 will be the first 100th anniversary Aero so I will be getting it a little sooner than I first thought (was going to be March 09, now Jan 09).
The concensus from the Morgan garage is to consider selling my series 3 now whilst it still has factory warranty and relatively low miles

My series 4 is likely to be matt black like my Carver and my Chop but with a little bit of clour inside to liven it up.
Also, I will be going for the autobox. Still not sold on the sidepipes, I like the quad sports set-up on the S4 but will go out in the S4 demonstrator to see if I can be persuaded to join the side pipe squadron.
