I note from the article in MOG mag, that the seats in the plus six were deemed to be comfortable. Mag bias probably, certainly proves a test drive may change your perception Rich.
That is an interesting comment in MOG mag and as you say there could many reasons for printing that.
We definitely will take a test drive in a Plus Four at some stage but the enthusiasm and desire has vanished for a while after yesterdays mindful 100 miles in the Plus 8, combined with the seats and unresolved brake issues on the new model.
