There was no connection between Borgward and Glas, but Frua liked to create slightly altered designs on different chassis. And his design for the Glas 1500 prototype (which was to become the Glas 1700 production car) was based on this Hansa 1300, which had no future when Borgward went bankrupt. By the way, Frua's Glas 1300 GT was warmed up for the Ford Mexico Coupé and the Ford Monte Carlo GT, after Glas went out of production.
