Mga tsikoteers please answer this..

Assuming the odometer reading is flawless and accurate and nobody had tampered it before and the car is well maintained..Question.

Can we safely say that the odometers reading is relative to the age of the car assuming a normal usage of 20Thou km per year?

Example: A 1996 (10 year old) car's odometer reads 74thou KM and using as our gauge the normal usage of 20thou km/year..safe to say that this 10 year old car is only 4 years old if we considered its low mileage? In short kahit matanda na ung car pero mababa pa ung odometer reading nya, fresh pa rin sya dahil mababa mileage nya?

Please guide me on this..Thanks.
