You probably want to stay away from resetting the odometer as it is deemed as a fraud. However, you probably would have heard that changing the engine resets the value. Wrong! If you think by changing the engine you might get higher resale value for your car, you might be committing a mistake. To reset, you have to replace the entire car components from the engine, transmission, suspension, brakes, alternator, wiring, and anything else you can imagine or have been told to.
