When considering wear and tear on a used car, inspection should involve assessing both interior and exterior signs that can provide valuable clues about its general condition and mileage. For example, examining the condition of the pedals, steering wheel, and seats is crucial. If these elements show significant wear, it can suggest that the car has experienced substantial use, potentially aligning with the odometer reading. On the other hand, excessive wear on these components with low mileage displayed on the odometer may indicate possible odometer fraud. Additionally, external signs like rust offer further insights into the vehicle's history and potential red flags if they don't correspond with the reported mileage.
