Fiat X 1/9
Behind this strange name lies one of the most interesting, affordable sports cars of the ’70s. Fiat presented the X 1/9 in 1972 as a tiny two-seater with a T-Top. Also, it came with a mid-mounted engine and two trunks: one in the front and one in the back. Just think of it as a Porsche Boxster, only 20 years older.
Despite its fantastic looks and technical layout, the X 1/9 was underpowered. It got just around 60 HP from its small 1.3-liter four-cylinder engine. And because the performance could have been more impressive, most owners decided to add bigger engines (via Motor Trend).
