I agree that it is not as balanced as an original Aero, the curves of the Aero mean that a downward flowing boot is a better match to my eyes. It continues the visual flow of the car from the side view.
The more round Lancia rear lamp assembly means it has a flat boot top and curved rear. On the Max this naturally flows from the roof design and maintains the visual line.
On this car I feel it makes the backend looks a little like an AC Cobra from the side view which is not as well integrated. The flow comes from the running boards as much as the cockpit/deck line and this is where it is slightly less resolved for me personally. Then again I would never claim my personal taste is better than whoever was bold enough to do this work.
I do think they have done a remarkable job in terms of the quality involved. I applaud their desire to make this one-off after all Morgan is about the hand-built aspect of a car. I like the idea that Morgan have re-bodied the Aero chassis like Hooper used to do for Bentley all those years ago. It is nicer to be aligned with a skill like that than the niche busting weird world of current mass market brands.
I have seen a lot worse home-grown projects in other brands. The Rolls-Royce estates from Dubai that were sold a few years back and even some of Porsches own 80's flat nose cars stand out as bad examples for me.
The question is what comes next from the chief pencil sharpener ?
