>I disagree. You can mess with odometer as much as you like. Trying to sell it off with a different amount of miles than have actually been put on it is called fraud.

For a long time this was just a fact of buying any car that lived long enough. I have bought several cars where the transaction went something like: "so the odometer has rolled over twice; so there's actually 376,000 miles on the frame... but only 118,000 of those are on this motor and I swapped the transmission with a reman 76,000 miles ago."

Of course we've added a few significant figures to odometers since then, and in the era of digital odometers I imagine "rolling over" behaves very differently. (Will the chassis survive 4 billion miles? Seems unlikely. Do the display and storage have different bit resolutions? Is it a saturating counter internally? Externally?)
