I saw this Porsche 965 group C car in action on track during the 2014 Ayrton Senna Tribute at Imola racetrack. The car (chassis #104) was built in 1983 and bought by Joest Racing which used the car in many races between 1983 and 1986. In 1984 the 956-104 took part in the 1000km of Nurburgring Nordschelife with Ayrton Senna, Henri Pescarolo and Stefan Johansson. The Porsche 956 is moved by a 2.65L turbocharged Flat-6 engine which is able to produce around 635 hp. Nowdays the car is owned by Alexander Seibold.
