I took my pictures from a specialist Dixi site, where it is listed along many other specials.
The Ihle identification probably comes from Bonham's auction site where the car was offered last year for 30,000-35,000 pounds, but not sold. It wouldn't be the first time that a car gets a "creative" description in the sales ad. There it is described as a 1927 Dixi DA1, while the plate on the car says DA1 1928 and the car carries a BMW sign which would make it a 1929-1932 car. Even the barchetta description is not authentic, because those cars were named Zweisitzer or Roadster in Germany back then, but not barchetta. Ihle was not a specialist coachbuilder offering individual coachwork, but made its money with standardized bodies, later on even offering the same body for chassis from different makers. If you take a closer look, no parts on the puzzle car are like those on the Ihle cars: the radiator mask is edgy, not curved; the hood louvers are different; the wheelbase looks increased to me; the Ihle bodies with the pointed rear didn't have doors; the general body lines on the puzzle car look much more crude than those on the Ihle cars ...
