Hi Dave,
Once you've done the recommissioning you mention, I'm sure it will ideal and provide a lot of pleasure.
One thing to check - and you probably already done it! - is what version of the Aero 8 S1 roof it has. The roof changed a few times within the first series and did improve with the revisions (become less and less prone to water ingress).
I will also be interested to see which interior door panels your Morgan has. These were revised through the life-cycle of the S1 to provide improvements on the interior room; while minor revisions, at best, some of the styles do allow for a little better elbow room.
Again, congratulations on your new car and welcome to the site.
