Which is More Important for a Used Car: Mileage or Age?

[LaJulian]

Mileage is more important. Below are the relevant details: Speedometer and Odometer: The speedometer indicates the vehicle's speed in km/h (kilometers per hour). The odometer actually consists of two meters: one is the speedometer, and the other is the odometer. The odometer is generally located directly in front of the driver's position. Working Principle: The odometer is a digital instrument that operates through the engagement of the counter drum's transmission gear with the worm gear on the speedometer's rotating shaft, causing the counter drum to rotate. Its characteristic is that when the upper-level drum completes one full rotation, the lower-level drum rotates 1/10 of a turn. Similar to the speedometer, modern odometers also include electronic versions, which obtain mileage data from speed sensors. The accumulated mileage data in electronic odometers is stored in non-volatile memory, allowing the data to be preserved even when the power is off.
