1969 Fiat 128 Saloon

Although its simple styling hinted at an update of the 124, what nestled under the skin makes this one of the most important cars of the 1960s. The 128 remains a Dante Giacosa masterpiece – powered by a transverse ohc engine, and driven by the front wheels via an end-on gearbox. It’s the recipe for technical orthodoxy that has since been adopted by the entire industry. Despite that, and being a great car to drive, shoddy build and horrendous rust means few survive, and it’s still rather unloved. But its sheer rarity in the UK guarantees that values are heading the right way.
