I have noticed on three different "speed guns" or radar speed displays that my 04 cambiocorsa coupe odometer reads approx. 5 mph higher in the car than shown on the speed gun/display. (The office where I work has a long straight entraance road and our safety guys installed the speed detector displays on the road to remind us to be safe. Plus, I noticed it on a similar display on a "highway" near me a couple times. I think I saw something posted on here a few months ago about similar results occurring with others here.
So, my question is: If the speedometer is showing I'me driving more miles per hour than I really am, is the odometer ALSO showing I am driving more miles than I really am? If that's true, then some of us may actually have 5% to 15% less miles on our cars than the odometer shows. That's great for the engine life, etc. but shows more miles at time of resale of course.
Does anyone know whether the odometers are correct, even if the speedometer is off several %, and whether it reads higher than the actual miles traveled?
