One of the best and most interesting classic American compact cars was definitely the legendary Plymouth Valiant. With striking styling, smaller dimensions, and engines, the car had a unibody construction and standard suspension, which included front A-arms and leaf springs set up in the back (via AC).
Under the hood was the Slant Six engine, which was new for 1960 and later became one of the most durable engines Chrysler has ever built. In the Valiant, it was available in two forms – 170 and 225 cubic inches. The Slant Six characteristic became one of the Valiant’s most significant selling points, and the car had decent performance and good fuel economy, even by today’s standards.
