I know I'm going to sound like a grandpa when I say this, but this is a big reason why I don't trust digital ODO'd in the first place. It can't be that hard to change any odo in any car, so why not figure it out? A few minutes and a computer could get you a few hundred or even thousand dollars on even the crappiest of cheap cars.
You don't need to own a supercar to justify digitally altering an odo, you could make profit on a Toyota Corolla.
Doing this on an analog odo would be far more difficult and deterring for the younger lazy generation.
