Used Car Terms Explained

Clear definitions for the condition terms, paint defects, and inspection vocabulary used in Dr.Vin assessments.

Condition Grade
A 0-100 score representing the overall visible condition of a vehicle based on photo analysis. Higher scores indicate better condition with fewer issues detected.
Component Grade
An individual condition rating for a specific area of the vehicle (paint, body, tires, interior, glass, undercarriage). Each component is graded independently to show where issues are concentrated.
Clear Coat
The transparent protective layer over a vehicle's paint. Clear coat failure appears as white, cloudy, or flaking patches, most commonly on horizontal surfaces like the hood and roof.
Orange Peel
A textured, bumpy paint surface resembling the skin of an orange. Often indicates a respray or factory paint defect. Visible under certain lighting angles in photos.
Panel Gap
The spacing between adjacent body panels (doors, hood, trunk, fenders). Inconsistent panel gaps can indicate prior collision repair or poor body work.
Paint Depth
The thickness of paint on a body panel, measured in mils or microns. Abnormally thick paint suggests a panel has been repainted, possibly to cover damage.
Curb Rash
Damage to wheel rims from contact with curbs during parking. Appears as scratches, scrapes, or gouges along the outer edge of the wheel.
Tread Depth
The remaining depth of the grooves in a tire's tread pattern. New tires have 10/32" of tread. Below 4/32" indicates the tire should be replaced soon. Below 2/32" is unsafe and illegal in most states.
Pre-Purchase Inspection
A hands-on mechanical inspection performed by an independent mechanic before buying a used vehicle. Covers engine, transmission, suspension, brakes, and other systems that cannot be assessed from photos alone.
Confidence Indicator
A rating attached to each finding in a Dr.Vin assessment reflecting how certain the AI is about the detection. Higher confidence means clearer visual evidence. Not a statistical probability.
Dollar Impact
An estimated cost range for a detected issue, based on typical repair and reconditioning costs. Calculated using Monte Carlo simulation with publicly available industry data.
Repaint Evidence
Visual signs that a body panel has been repainted, including color mismatch between panels, overspray on trim or rubber seals, orange peel texture differences, and tape lines.
