In the May copy of Octane Charles Morgan states "800" odd whilst on the Morgan web site says the figure is 650
Not as far apart these figures as you think Steve, 650+ Aero 8's to-date (or when the website was updated) and 100 AeroMax's by end-June or so, gives 750+. Maybe the now smallish difference is just due to Charles's penchant for rounding-up
