Which of the following are indicators of underlying vehicle damage after a collision?

Misaligned doors and uneven gaps are clear indicators of underlying vehicle damage after a collision because these issues suggest that the vehicle's structural integrity has been compromised. When a vehicle is involved in a collision, the framework can become bent or misaligned, which can lead to noticeable differences in the positioning of body panels and doors. Proper alignment is crucial for the overall performance and safety of the vehicle; if the gaps between the panels are not uniform or the doors do not align correctly with their respective frames, it often indicates that the vehicle has suffered damage beyond just superficial scratches or dents.

In contrast, the other options do not typically suggest significant underlying damage. Low fuel levels and engine noise do not relate to structural issues resulting from a collision. Clear paint finishes and new tires might indicate maintenance or cosmetic repairs rather than damage. Lastly, high coolant levels and smooth steering usually signify that the vehicle's engine is functioning well, and they don’t point to any hidden damages from a collision.
