172/Km/hour Citroen Gs Club Revers Max Speed If You Try To Test This French Cars

172 km/hour revers max speed of the Citroen Gs Club from 1976 :)
The car in revers is very stable really easy to control because of the hydraulic system suspension. I could not test the real speed in revers because the odometer is going backwards as well so it made the top speed 172 km/hour.
but it is around 50km/hour .
