When I talked to a repair technician at VDO (before they closed their Winchester VA repair facility) she pointed out that thse 201/124 speedometers were far more fragile than earlier ones. I have owned 6 201s and 124s. I have had to repair/replace 3 odometers at between 100-200kmi and could have set the mileage any number I wanted. I have gone out of my way to set two of them at the correct mileage (and stuck a used speedometer with about the correct mileage into the 3rd). Many states don't even bother to record numbers in excess of 100kmi.
