Actually my neighbour had a Metro and boy could that thing move. The

As I said - a very optimistic speedo. Some makers today do just the same.
When making one which is within 1% accuracy should be child's play since
they are counting pulses.

To e-mail, change noise into sound.
Years ago when speedometers were mechanically driven I had a Cortina with
an automatic box. I had always thought it was very noisy at 70 or so mph
so I had a friend trail me one night. THe speedo was under reading byt
about 8 mph. I often wondered ift they had fitted the wromng cable
Why do you believe that your friends speedo was accurate?
A wrong cable cant change the the accuracy but its not unknown for the
wrong speedo drive gears to be fitted to the box resulting in
under-reading. Happened with my wifes old Citroen ZX and it had to be
recalled.
