5 signs that a used car may be accident-free.

1. Paint Issues - Some may have patches, whether it's just a slightly different shade, different gloss, or a complete color mismatch between different body panels, these all indicate a car that has had its body repaired. However, double check with the seller.

2. Replacement parts - Many drivers look for fillers to fill dents and cracks on their cars. While filler can help some dents disappear with virtually no blemishes left, the mixture can be harmful to the car's body if not mixed properly. Filler mixtures can cause cracks around dented areas, discoloration, and weakened areas that are susceptible to general wear and tear over the long term.

3. The car does not run straight - When the car cannot run straight, it means the alignment has been lost. In the worst case scenario, it could even be a car with a bent chassis that cannot be properly aligned. Never buy such a vehicle without having a tune-up done, if possible, and making sure the problem is fixed.

4. Visible Crease Panels - The flexible steel panels that make up most cars can wrinkle in collisions, and proper repair work will keep the car's body as straight as possible. However, poor repair work can cause hidden areas such as the trunk floor or parts of the engine compartment to remain visibly wrinkled.

5. Uneven tire wear - Tire tread wear on one side more than the other can be a sign that the vehicle has been in an accident. Check the frame around the tire as well as the rim to see if they are scratched or dented. That could be a sign that the car has been in a serious accident.
