i'm confused myself. looking at MMC's own site you'd think there's more difference between a 4/4 and a Plus4 than a Plus4 and Plus6. i so wanted to love it and consider it for myself, but in the flesh.... it's a Plus8. i've just looked at wikipedia and Parkers, everyone quotes different widths!
From Morgan Motor Co Data
Length +8 = 4150, +6 = 3890, Roadster = 4010
Width +8 = 1840, +6 = 1746, Roadster = 1720
So, the +6 is shorter than both the Plus 8 and Roadster, narrower than the +8 but wider than the Roadster.
