The Porsche 914 was a lightweight, mid-engined go kart that comes with not one, but two roofs. Built in the late 60s to mid 70s, this was Porsche’s entry level model that replaced the 912. It features a targa style top, hence the two roofs (one with a sunroof and one without), a 2.0 liter middle mounted flat 4 engine that produces almost 100 hp, and, specific to this model, brand new wheels and tires. This 1974 Porsche 914 2.0 was spotted at Frankman Motors in Sioux Falls, SD and is currently for sale for $23,000!
