I am not particularly concerned about the legalities of a badly caliberated speedo, it just annoys me that my speedo is 8% out, in the "legal" window still but niether the factory or the dealer will do anything about it, as it is "legal" if it is less than +10%. It is just bad engineering that they are happy that it is "legal" rather than right. As I have said before, it must be just a small matter of a recal with the correct datum number to make it work accurately. Lotus manage it! I can even sort it out on my bicycle computer but it seems to be beyond Morgan and the dealers.
