I have driven both and I would choose the autobox over the manual on the Plus Four. As said earlier, the manual box ratios are too long for sporty driving and the auto feels much sportier, despite the lack of clutch pedal, and is also 1/2 a second quicker to 60mph and gives better mpg.
I am a manual box diehard, but in this instance I am prepared to admit the 8 speed ZF box is a better choice. You need to have driven both to realise why but don't worry, you will not be disappointed.
The Plus Six may be a different story though. but it is unlikely that we will ever find out as Morgan have no plans for a manual Plus Six anytime soon (AFAIK).
