The prewar notion that streamlined-looking fastback styling was the wave of the future was largely abandoned, though every GM division did market some fastback models for 1949. Chrysler did the same, but on a much smaller scale. Plymouth built an entry-level fastback 2-door sedan, and Dodge had a semi-fastback similar in character to Mercury's '49 roofline.
And there was even more Chrysler experimentation in Dodge's Wayfarer line. This experimentation required extra tooling expenses for what turned out to be fairly low-volume cars. In those days, Chrysler Corporation ranked ahead of Ford in sales and was doing well financially, so its management must have thought that the risk of losing some money to gain market knowledge was worthwhile.
Let's take a look at Dodge's Wayfarer line. Color images are of cars that were on Internet for-sale sites.
