This car is quite special. The video notes that thhe Pegase Boattail Roadster was by Jacques Soutchek, but that may not be the case.
The tiny Amilcar company of Paris certainly shared much of the Soutchek style shown in various custom Delehaye's and Bugatti's -- a style which was typically hand-formed alloy and steel by only a small group of skilled craftsmen like Mr. S.
Overall, the Pegase Boattail Roadster is most notable for its rarity and immaculate presentation, if not its sheer pace or the grandeur of some of the gigantic Delehaye's and Bugatti's from this interwar period.
