My 2008 Morgan Plus 4 has a speed sensor connected to the gearbox. After 74000 km it has failed so that the speedometer does not work. The speed sensor is no longer available so I will have to "upgrade" to a wheel speed sensor as used on later models. I remember cheap cars from the seventies (citröen 2cv and citroën gs) running for hundreds of thousands kilomrters with mechanical speedometers without any problems. I am not sure that evolution always is for the better.
