The Buick Caballero was a short-lived, but stylish station wagon from the GM division. The Caballero was a pillarless model, using a steel body, which was an improvement over the original, wood wagons. For just 1957 and 1958, the Caballero provided buyers with a new Buick that sat in the entry-level position for the brand. Today, the Buick Caballero has proven to be more popular as a collectible than it ever was new. The retro styling with iconic elements from the 1950s and the sturdy structures, mean that these wagons survived the years well. You can track one down for your collection at FossilCars.
