Fiat X 1/9
Behind this strange name lies one of the most interesting affordable sports cars of the ’70s. Introduced in 1972, the Fiat X1/9 was a small two-seater with T-Tops, a mid-mounted engine, and two trunks. Think of it as a Porsche Boxster, just 20 years older (via Classics World).
Despite fantastic looks and technical layout, the X 1/9 was pretty underpowered. With just around 60 hp from its small 1.3-liter four-cylinder engine, its performance was not impressive and most owners decided to fit bigger engines.
