I believe the E85 has the sleekest profile because of the proportions I've highlighted in yellow.
Imo these over-hangs and arch heights are so important and give the Mk1 a lower more compact and classical 2-seater roadster feel.
The problem with doing what you've done there Colin, is that the images aren't to scale - the E85 is also at a slight angle which complicates matters further. I've rescaled the images slightly so that the proportions align with the real-world (e.g. E85 wheelbase = E89 wheelbase), rotated them so the cills are level and added some feature height comparison lines at various points...
