you would simply think that the system would refuse an entry with the message "new figure cannot be less than old figure" - but yes I know, that would be too obvious

Not sure how a 'government system might prevent' this happening ??

Hmm - another vote for joined up thinking?

It might be that the odometers are as unreliable as the rest of the vehicle apparently is from what i read, new ones probably cost more the vehicle is worth, used odos are being fitted?

It's pretty pointless clocking cars and leaving the evidence for all to see by having the car MOT'd with less miles than last time, only a lunatic would try such a thing unless the typical buyers are even dafter and never look at MOT history, more sensible would be to clock the car annually just before MOT, but if the vehicle is serviced by a proper garage the discrepencies will still show up.

Clocking has to be done better than this to be worth doing, or are buyers really so gullible.
