What can be a consequence of neglecting the inspection of repairs?

Neglecting the inspection of repairs can indeed lead to costly future repairs. When repairs are not inspected, there is a risk that underlying issues may go unnoticed, which can lead to further damage over time. For instance, if a repair on the frame or structural integrity of a vehicle is not thoroughly checked, it could lead to alignment issues or safety concerns that become more severe and expensive to address later on. Regular inspections ensure that repairs are completed correctly and that any potential problems are identified early, ultimately saving the vehicle owner from incurring high repair costs in the future.

The other options do not accurately reflect the potential consequences. Ignoring inspections can certainly affect a vehicle negatively, especially regarding safety and functionality. While it's true that a warranty denial could occur under certain conditions, it is not a definitive outcome of neglecting inspections. Additionally, neglecting inspections does not enhance the visual appeal of a vehicle; instead, it may lead to visible signs of wear or damage that detract from its attractiveness.
