Which aspect does NOT typically require adjustment during an auto appraisal?

In the context of auto appraisals, the aspect that does not typically require adjustment is manufacturer recalls. Manufacturer recalls are safety-related issues identified by the manufacturer that often require repairs or replacements to be performed at no cost to the vehicle owner. These recalls are generally considered as part of the vehicle's condition but do not usually impact the appraisal value in the same way that physical attributes or modifications would.

On the other hand, mileage changes significantly affect the value of the vehicle, as lower mileage typically correlates with less wear and tear. Color and aesthetics can play a role in desirability and, consequently, the appraised value of the vehicle, as certain colors may be more appealing in the resale market. Aftermarket modifications can also affect a vehicle's value, either positively or negatively, depending on the nature of the modifications and how they align with market preferences.

Hence, while recalls are essential for maintaining safety and can affect ownership perceptions, they do not require value adjustments during the appraisal process like other aspects might.
