The 1938 Adler Type 10 2.5-litre two-door cabriolet (chassis 185535) is a rare Karmann-bodied example of Adler's aerodynamically advanced streamliner range, introduced at the 1937 Berlin Motor Show. One of only a handful of two-door cabriolet variants known to survive, it underwent a comprehensive restoration around the late 1970s by a former Karmann craftsman. The car retains a well-preserved patinated interior and was awarded second place in Class 1 Pre-war at the 2018 Techno Classica Essen FIVA Concours d'Élégance.
