19. Buick Roadmaster Estate Wagon
Although the Roadmaster Estate Wagon was the least popular body style in Buick’s lineup, it introduced the station wagon as a category in the American car industry. Of course, there were numerous wagons before it, but they were all sedan delivery cars for commercial purposes. When they presented the Roadmaster Estate in the late ’40s, it changed the game. Suddenly, there was a fresh and interesting long roof they based on those luxury models. It came with a powerful engine, wood grain details, upscale equipment, and prestige.

This model showed that people carriers and station wagons can be cool, although few customers purchased this special model. They produced 80,000 standard Roadmasters in two and four-door variants per year. But they only built several hundred Roadmaster Estate Wagons. And that was not enough to make Buick any money, yet enough to start a trend.
