'Robbo To the Rescue' again by the sound of things Dano but why not see what a GPS is reading whilst driving ? Sit it somewhere where you can see both speedo and GPS. You'll get an accurate difference then and could always drive on the GPS until ready to go through the trauma of speedo change if you really consider it necessary. I did it with Poubelle and now I know I worry far less and even sleep better ! It all comes down to how pedantic one is and what you can live with I guess. As I have another complete speedo who knows I might get bored enough to do a change over some day? Having one that over reads does wonders for the ego though
With accurate GPS readings it becomes an easy matter to follow Julian
