There's a member on another forum i'm part of, and he has recently come across what he thinks was a car that was previously his, but was in a wreck. This car looks exactly the same; same mods, same rims, same interior bits, but the selling dealership has repaired all the front end damage, and the odometer is reading around 26K miles, but his car had around 57K or so. His was totalled, but they are saying it was never in an accident, and they even changes one letter in his VIN, from a U to a V. So, my question is, how hard is it to turn back a digital odometer? WHat does it consist of? New ecu? New gauge cluster?
