The Exner-era cars have a bad reputation, but it wasn't Virgil's designs that caused this it was the corporate big wigs at Chryslers. Virgil Exner was a meticulous designer. Today people mostly remember the decadent fins of the late fifties and equate them to Exner. The fin was only one of many design elements incorporated into these cars. All fins are not created equal, however. Exner actually tested models of his designs on a wind tunnel to get the most efficient aerodynamics. This is how he came to the conclusion that the canted fin was best. Unlike Exner, GM's designers tacked on inefficient straight up style fins on their cars. The casnted fin proved itself in wind tunnel test to have the best aerodynamics and ability to cheat the effect of cross winds. This is why Mopars have canted fins rather than straight up fins. The design that we know as "Forward Look" was originally slated for the 1960 model year. As I mentioned before the big wigs wanted to push the production of these designs three years forward for 1957. While they did steal GM's crown, the rush of these cars into production meant poor quality control. This is the true reason why these cars rusted prematurely. The fin era ended as abrubtly as it started. While today nouveau folks think that winged cars are laughable. In the late 50's they pointed the way to a future that wouldn't arrive.
