The Porsche 914 or VW-Porsche 914 is a mid-engined sports car designed, manufactured and marketed collaboratively by Volkswagen and Porsche from 1969 to 1976. It was available as a targa-topped two-seat roadster powered by either a flat-4 or flat-6 engine. A great deal of attention must be placed when evaluating this market, as many vehicles have gone through engine conversions and modifications over time.
