My Plus Four is 22MY and follows on from a Plus 4 with an Everflex hood and a Roadster with Mohair. My initial thoughts are that it is noisier than either of the earlier cars although Morgan say the new 22MY hood is quieter than the original Plus Four hood. I cannot comment as I have not tried a 21MY car with the hod up.
The draught/gale at the back of the sidescreen is certainly worse than both my Plus 4 and Roadster.
I have only had the opportunity to drive the car in light rain where it did not let in any water at all. I am still waiting for the opportunity to try it n heavy rain. I will report back when I do.
Best regards,
John
